A display device includes a display panel having an upper surface and being configured to display an image, a mold frame configured to receive the display panel, and a lower receiving member having an inner wall disposed on a peripheral area thereof and being configured to receive mold frame and the display panel. The mold frame includes a peripheral area disposed around an open portion of the mold frame, and a side wall disposed in the peripheral area. The side wall of the mold frame is connected to the inner wall of the lower receiving member, and the panel supporter of the mold frame is disposed on the upper surface of the display panel to support the display panel.

Display device and method of assembling the same

A printed circuit board (PCB) includes a base substrate, an electrical wiring, a dummy pad and a thermally conductive adhesion member. The base substrate includes a light-emitting diode (LED) mounted on a first surface of the base substrate. The electrical wiring is electrically connected to the LED. The dummy pad is formed on the first surface to be connected to the electrical wiring. The thermally conductive adhesion member is attached to a second surface of the base substrate. Therefore, superior heat radiation may be obtained, thereby reducing or preventing damage to the LED and the LCD device using the LED by radiating the heat from the LED used as a light source.

A light guide unit for a point light source includes a light incident portion, a first reflecting portion and a second reflecting portion. The light emitted from the point light source enters to the light incident portion. The light incident portion includes an optical pattern diffusing an incident light corresponding to the point light source. The first reflecting portion reflects a first light of the incident light. The second reflecting portion roundly connects the first reflecting portion to the light incident portion and reflects a second light of the incident light.

Display device having light guide unit

A light-guide plate includes a body for guiding incident light, and at least an inserting portion penetrating a portion of the body, wherein at least a light source for providing the light-guide plate with the light is inserted into the inserting portion. The inserting portion can be formed at an end portion of the body. A side surface of the body can be recessed to form the inserting portion. A light-diffusing pattern can be formed at a side surface of the inserting portion, and the side surface of the inserting portion is substantially parallel with the side surface of the body.
