    Abstract: A composite sheet includes a first sheet and a second sheet. The first sheet includes a first substrate and a first optical pattern layer disposed on an upper surface of the first substrate. The second sheet is disposed on the first sheet. The second sheeting includes a second substrate and a second optical pattern layer disposed on an upper surface of the second substrate. An extending direction of the first optical pattern layer intersects an extending direction of the second optical pattern layer such that an intersection angle of the extending direction of the first optical pattern layer and the extending direction of the second optical pattern layer is in a range of 40° to 70°.

    Abstract: A reflection sheet and backlight unit including the same are disclosed. In one aspect, the reflection sheet includes a bottom surface, a plurality of side surfaces, each extending from the bottom surface and having an edge opposing the bottom surface, and a first cutting line formed in at least a first one of the side surfaces from a boundary between the first side surface and the bottom surface toward the opposing edge of the first side surface. The reflection sheet also includes a cover surface extending from the opposing edge of the first side surface, wherein the cover surface comprises a protruding surface protruding toward the first cutting line.

    Abstract: A display device includes a display unit having pixels, a touch sensing unit including touch electrodes disposed on the display unit, and a touch driver configured to supply a touch driving signal to the plurality of touch electrodes and receive a touch sensing signal from the touch electrodes. The touch driver supplies a first touch driving signal having a first phase to one or more first touch electrodes, and supplies a second touch driving signal having a second phase opposite to the first phase to one or more second touch electrodes, at least a part of which is disposed across a specific point from the first touch electrodes. The touch driver receives a first touch sensing signal having the first phase from at least one of the first touch electrodes, and receives a second touch sensing signal having the second phase from at least one of the second touch electrodes.

    Abstract: An optical member and a display device including the same. The optical member includes a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.
