Abstract: Provided are a composite optical sheet and a liquid crystal display device including the same. The composite optical sheet includes: a first optical functional layer having a first surface and a second surface, the first surface including a reference plane and a pattern of recesses dented from the reference plane; a first support layer disposed on the first surface of the first optical functional layer; a first adhesive layer disposed between the first optical functional layer and the first support layer, wherein the first optical functional layer is coupled with the first adhesive layer by penetrating into the first adhesive layer at least partially; a second optical functional layer disposed on the first support layer and including a pattern of prisms extended in a first direction; a polarizing layer disposed on the second optical functional layer; and a second adhesive layer disposed between the second optical functional layer and the polarizing layer, wherein the second optical functional layer is coupled with the second adhesive layer by penetrating into the second adhesive layer at least partially.

Abstract: A display device including: a substrate having a display area and a non-display area extending around the display area, the display area having emission areas and a light blocking area; a thin film transistor layer on the substrate and including thin film transistors; a light emitting element layer on the thin film transistor layer and including light emitting elements; a wavelength conversion layer on the light emitting element layer to convert a peak wavelength of light provided from at least some of the light emitting elements; and a color filter layer on the wavelength conversion layer. The color filter layer includes: color filters in each of the emission areas; a first light blocking part in the light blocking area; and a second light blocking part in the non-display area.

Abstract: A display device includes: a first display panel; a first housing disposed on the bottom of the first display panel; a first cabinet disposed on the bottom of the first housing, the first cabinet including a first protrusion part and a first concave part; and a first side frame disposed on a side surface of the first display panel. The first side frame is movable toward the first cabinet, and a portion of the first side frame extends to the first concave part. Thus, there may be provided a display device which may be independently used and also be used to constitute (or form) a tiling display device by connecting multiple display devices.

Abstract: A backlight unit for a display device includes: a light guide including a light incident surface; a substrate facing the light incident surface; a plurality of light sources on one surface of the substrate facing the light incident surface; and a first member disposed between the substrate and the light incident surface to space the light sources apart from the light guide. The first member includes: a support on one surface of the substrate that do not include the light source, the support having a first surface facing the light incident surface and a second surface facing the light sources; and a first layer disposed on the first surface and the second surface of the support to improve luminance uniformity across the light incident surface.
