Abstract
An image display apparatus comprising a light guide plate, a light-emitting diode (LED), a first transparent substrate and a second transparent substrate is provided. Light generated from the LED is guided into the light guide plate through the edge thereof, and outwardly projected through the two opposite surfaces of the light guide plate. Thus, a pattern being disposed in front of the first transparent substrate or the second transparent substrate would be lighted up.

An image display apparatus, comprising:
- a light guide plate having a first light emitting surface, a second light emitting surface opposite to the first light emitting surface, and an edge;
- a light-emitting diode (LED) disposed adjacent to the edge of the light guide plate for projecting light towards the light guide plate;
- a first transparent substrate disposed adjacent to the first light emitting surface of the light guide plate;
- and
- a second transparent substrate disposed adjacent to the second light emitting surface of the light guide plate;
- wherein the light is adapted to be guided into the light guide plate from the edge thereof, and outwardly projected through the first light emitting surface and the second light emitting surface;
- thereby a pattern presented in front of one of the first transparent substrate and the second transparent substrate is capable of being lighted up.
