A light guide plate includes a light incident surface to which a light is configured to be incident, a light exit surface from which the light incident through the light incident surface is configured to exit, a bottom surface facing the light exit surface configured to reflect at least a portion of the incident light, and a scattering pattern disposed on the bottom surface. The scattering pattern includes a first protrusion portion protruding from the bottom surface, a recess portion disposed along a circumference of the first protrusion portion and recessed from the bottom surface and a second protrusion portion spaced apart from the first protrusion portion and disposed along a portion of the recess portion.

Light guide plate, backlight unit having the same, display apparatus having the same, and method of manufacturing the same

A display apparatus includes a display panel which receives light to display an image. A light guide plate guides the light toward the display panel. A light source unit is disposed at a first side of the light guide plate to provide the light to the light guide plate. The light source unit includes a printed circuit board which includes a first area and a second area. A first light source is disposed on the first area and generates the light. A first stepped part is disposed on the second area and faces the first light source. A first adhesive part is disposed on the second area. The first stepped part reflects the light which is generated from the first light source toward the light guide plate, and the first adhesive part attaches the printed circuit board to the light guide plate.

Backlight unit and a display apparatus including the same

A display device includes: a display panel which display an image using light; a light source which generates and provides the light to the display panel; a circuit board on which the light source is mounted; a fixation frame on which the light source and the circuit board are disposed; and a lower frame on which the display panel is disposed and in which the light source, the circuit board and the fixation frame are disposed. The lower frame defines: a bottom portion thereof overlapping the display panel, and an accommodation portion thereof extending from an end portion of the bottom portion and on which the light source, the circuit board and the fixation frame are disposed. The circuit board extends to cover the accommodation portion.

Display device including lower frame having accomodation portion extended from bottom portion

A display device includes a backlight assembly including a light emitting unit to emit a light and a display panel receiving the light and displaying an image. The light emitting unit includes a light emitting diode package, an optical lens, and a reflective layer. The light emitting diode package includes at least two light emitting diodes to emit lights having different colors. The optical lens covers the light emitting diode package and includes a first lens surface and a second lens surface changing an optical path of the light incident through the first lens surface. The reflective layer is partially disposed on the first lens surface.

Display device

A liquid crystal display includes a display panel receiving light to display an image, and a backlight assembly emitting the light to the display panel, the backlight assembly including a light emitting unit emitting the light, a light guide plate coupled to the light emitting unit, the light guide plate guiding the light emitted from the light emitting unit to the display panel, and a reflective adhesive member including a light reflective material, the reflective adhesive member surrounding the light emitting unit and coupling the light emitting unit to the light guide plate.
