Patent ID: 8511845

Claim:
A light generating device comprising: a first layer; a plurality of light source devices disposed on the first layer and configured to emit light, at least one of the light source devices including a light emitting diode for generating the light; a reflection layer disposed on the first layer and configured to reflect the light emitted from the light source devices; a second layer covering the light source devices and the reflection layer; a diffusion layer disposed on the second layer and configured to diffuse the light emitted from the light source devices; and an auxiliary layer having a plurality of light shielding members placed between the second layer and the diffusion layer, the light shielding members placed at locations corresponding respectively to the light source devices, the auxiliary layer being separated from the second layer so as to create a first air space between a surface of the second layer and surfaces of the light shielding members, the first air space extending along the light source devices.
