Discussed is a display device. The display device can include an optical frame, which provides light up to an edge of a display panel, thereby enlarging an active area of the display device.

Display device

Disclosed is a backlight unit and a display device including the same. The backlight unit includes a backlight configured to supply light in one direction, a case that accommodates the backlight, and a cabinet coupled to a top of the case, and configured to include a side wall which faces one direction. The inside of the case has a hive structure. At least one edge region of the case includes a stepped portion which is lower in height than a central region of the case to accommodate the cabinet.

Backlight unit and display device using the same

A curved surface backlight unit is disclosed which includes: a light source; a curved surface light guide plate disposed parallel to the light source; first patterns on one surface of the light guide plate; a reflection plate disposed under the light guide plate; optical sheets disposed on the light guide plate; and second patterns formed on one surface of at least one of the optical sheets.

Curved surface backlight unit and curved surface display device including the same

A diffusion sheet adapted to minimize brightness difference between lights progressing in its oblique directions is discussed. The diffusion sheet according to an embodiment includes: a base film; a first diffusion material layer formed on an upper surface of the base film and configured to have a haze range of about 10&#x2dc;40%; and a second diffusion material layer formed on a lower surface of the base film.

Liquid crystal display device comprising a second diffusion sheet having upper and lower diffusion layers wherein the upper diffusion layer includes multi-dispersed beads

A back light unit is disclosed, which improves condensing efficiency of light and viewing angle characteristics. The back light unit includes at least one lamp generating light, a light guide plate emitting light across a surface thereof using the light generated from the lamp, a diffusion sheet arranged above the light guide plate to diffuse the light passing through the light guide plate, a first condensing sheet condensing the light from the diffusion sheet using a plurality of first elliptical condensing patterns arranged on the diffusion sheet in a first direction, and a second condensing sheet further condensing the light from the first condensing sheet using a plurality of second elliptical condensing patterns arranged on the first condensing sheet in a second direction crossing the first direction.
