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.

A backlight assembly includes a light-guiding plate and a light-generating member. The light-guiding plate has a lower surface, an upper surface and a side surface at which a combining recess is formed. The light-generating member includes a light source and a body. The combining recess has a first side surface, a second side surface facing the first side surface and a light-entering surface connected to the first and second side surfaces. A first width of the combining recess adjacent to the side surface of the light-guiding plate is smaller than a second width of the combining recess adjacent to the light-entering surface. Moreover, at least a portion of the body of the light-generating member is for being inserted into the combining recess.

In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

In a light guide plate and a display apparatus having the light guide plate, the light guide plate includes an incident face and a first exiting face. The incident face receives a light provided from an exterior. The first exiting face includes a first area and a second area. A first light-controlling pattern is formed in the second area. The first exiting face guides the incident light to the first area by the first light-controlling pattern and exits the guided 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.
