An optical device is provided. The optical device is capable of varying transmittance, and such optical device can be used for various applications such as eyewear, for example, sunglasses or AR (augmented reality) or VR (virtual reality) eyewear, an outer wall of a building or a sunroof for a vehicle.

Provided is a display device including a window layer including a transmission area and a bezel area adjacent to the transmission area, a color layer under the bezel area, an adhesive layer under the transmission area, and a display panel under the adhesive layer, wherein the color layer and the adhesive layer may not overlap in a direction perpendicular to the transmission area.

A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

A display device according to the present invention comprises: a display panel; a middle cabinet for mounting the display panel; and a foam pad which is interposed between the display panel and the middle cabinet, and has a light absorbing material formed in either an area having a contact surface with the display panel or a contact surface with the middle cabinet. The display device of the present invention may be connected to an artificial intelligence module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to a 5G service, etc.

Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described.

A display device includes a window, and a decorative print pattern and an attachment assisting layer sequentially disposed on the window, wherein the decorative print pattern includes a first opening having a closed curved shape and exposing the window, the attachment assisting layer includes a second opening overlapping the first opening and exposing the window, and the second opening includes a first open portion exposing an edge of the first opening.

A display device and a method of manufacturing the display device are provided. The display device includes a first lamination member that includes a first area and a second area that is an area other than the first area; a bonding member disposed on one side of the first lamination member and that includes an adhesive resin; and a second lamination member disposed on the other side of the bonding member, wherein the bonding member includes a crack portion formed in at least a part of a matrix of the adhesive resin.

A display device includes a window including a planar portion and a bending portion that is bent from the planar portion. A display module is disposed below the window. The display module includes a central portion overlapping the planar portion and an edge portion overlapping the bending portion. An adhesive member including an adhesive layer is disposed between the window and the display module. A lubrication layer overlaps at least a portion of the adhesive layer.

The touch panel built-in display includes a first electrode, a second electrode, and a third electrode for detecting the pressed state in which the protective plate is pressed. The first electrode is provided in the peripheral region on the back surface of the protective plate. The second and third electrodes are provided adjacent to each other in the peripheral region on the principal surface of the sensor substrate. That is, the first electrode, the second electrode, and the third electrode are provided in the peripheral region as a configuration for detecting the pressed state.

A display device including a display panel having a folding area and a bending area, a support member disposed on a bottom surface of the display panel and including a plurality of openings formed in the folding area, an elastic member disposed on a bottom surface of the support member and overlapping the openings in the folding area, and a first adhesive member disposed between the support member and the elastic member.
