Patent ID: 8179503

Claim:
A pixel structure, comprising: a first substrate; a second substrate, substantially parallel with the first substrate and disposed over the first substrate; a liquid crystal layer, sandwiched between the first substrate and the second substrate; a reflecting structure, disposed on the first substrate; and a light angle control structure, disposed on the second substrate; wherein the light angle control structure is configured to reflect a light entering from the first substrate to the reflecting structure, and the reflecting structure is configured to reflect the light coming from the light angle control structure such that the light exits from the pixel structure in a predetermined direction; wherein the light angle control structure has a surface, the surface forming a first angle θ A with the second substrate, the predetermined direction being determined based on the first angle θ A , predetermined direction forming a second angle θ B with the second substrate and the second angle θ B being approximately (90°-2θ A ).
