Abstract: A reflection type display apparatus has a front light unit (FLU), and includes a display panel, a light guide disposed on the upper surface of the display panel, a light transparent adhesive layer attaching the lower surface of the light guide to the upper surface of the display panel, and a light source located at a side of the light guide for emitting light to the light guide. A protection window covers the light guide and the light source. By covering the display panel installed on the lower surface of the protection window and the light guide with a moisture-proof and light-shield film, moisture-proofing and light-shielding effects are obtained simultaneously. Further, by forming a light absorption layer at the edge of the light guide adjacent to the light source, generation of a hot spot at the edge of the light guide may be inhibited.

Abstract: A keypad assembly including a light guide plate, a keypad, and reflective layers is disclosed. The light guide plate includes reflective patterns that are locally formed on the bottom surface of the light guide plate to reflect a part of light going into the light guide plate to the top surface of the light guide plate. The keypad includes a pad that is in the shape of a box whose bottom is opened by sidewalls and surrounds the remaining portions of the light guide plate except for the bottom surface of the light guide plate and at least one key button placed on the top surface of the pad and outputting light reflected from the reflective patterns to their outside. The reflective layers are formed at the sidewalls of the pad facing the sides of the light guide plate to reflect light irradiated from the sides of the light guide plate back to the sides of the light guide plate.
