Patent ID: 8085371

Claim:
A reflective liquid crystal display comprising: a first substrate; a second substrate having a display region; a liquid crystal layer between the first substrate and the second substrate; a polarizer placed on an outer side of the first substrate and having a transmissive axis, the outer side being opposite to the liquid crystal layer; a quarter wavelength retardation plate arranged between the first substrate and the polarizer, the quarter wavelength retardation plate comprising: a half wavelength retardation film of a predetermined wavelength, wherein a slow axis thereof makes a angle of Θ 1 with the transmissive axis; and a quarter wavelength retardation film, wherein a slow axis thereof makes a angle of Θ 2 with the transmissive axis in accordance with relation equation of Θ 2 =2×Θ 1 -45 degrees; at least one pixel disposed in the display region and including a thin film transistor; and an organic insulating layer covering the pixel, wherein an effective light path difference Δnd of the liquid crystal layer is equal to a quarter of the predetermined wavelength.
