PHASE DELAY ELEMENT FOR TRANSMISSIVE AND REFLECTIVE TYPE LIQUID CRYSTAL DISPLAY |
摘要 |
A phase delay element includes a brightness enhancement layer intermediate a reflection layer and an artificial light. The brightness enhancement layer is defined by a first surface and an opposite second surface. The first surface faces the reflection layer. A first light from the artificial light is incident on the second surface. A phase of the first light is delayed by about 1/4 phase (λ/4) so that a second light is emitted from the first surface toward the reflection layer. The second light is reflected from the reflection layer so that a third light is emitted from the reflection layer toward the first surface. A phase of the third light is delayed by about 1/4 phase (λ/4) so that a fourth light is emitted from the second surface. Therefore, a portion of the artificial light, which is reflected from the reflection layer, is recycled to improve a luminance of an LCD apparatus.
