  • Publication number: 20090284949
    Abstract: An optical element includes a light-transmitting structure and a first reflection-prevention layer. The light-transmitting structure has a first surface and a second surface facing the first surface. The first reflection-prevention layer includes a plurality of first light-refractive index buffering particles deposited on the first surface such as the concentration of the particles decreases as the distance from the first surface increases. The first reflection-prevention layer decreases the variation of a light-refractive index from the light-transmitting structure to an air layer to decrease the light reflectance of the first surface. Therefore, the light transmittance of the light-transmitting structure is increased due to the reflection-prevention layer formed on a surface of the light-transmitting structure, so that luminance may be enhanced. Moreover, the reflection-prevention layer may enhance the resistance of the light-transmitting structure to external impacts.
