Patent ID: 7505095

Claim:
A display panel, comprising: a first substrate having a first alignment surface in a first alignment direction; a second substrate parallel and opposite to the first substrate, having a second alignment surface in a second alignment direction; liquid crystal molecules disposed between the first alignment surface and the second alignment surface; a first polarizer having a first absorption axis and disposed over the first substrate; a second polarizer having a second absorption axis and disposed over the second substrate, wherein an angle between the first absorption axis and the first alignment direction as well as an angle between the second absorption axis and the second alignment direction are in a range of about 45°±10° respectively; a first optical compensation film having a first optical axis and disposed between the first substrate and the first polarizer; a second optical compensation film having a second optical axis and disposed between the second substrate and the second polarizer, wherein the first optical axis and the first alignment direction as well as the second optical axis and the second alignment direction are in parallel; and a third optical compensation film disposed between the first optical compensation film and the first polarizer, wherein the third optical compensation film satisfies a relation nx=nz≠ny or ny=nz≠nx, wherein nx and ny are in-plane main refractive indices and nz is a thickness-wise refractive index.
