Deviation in phase difference of the light passing each of the red, green, and blue dots, i.e., 2 pi *( alpha *dR* DELTA nR+ReR)/ lambda R, 2 pi *( alpha *dG* DELTA nG+ReG)/ lambda G, and 2 pi *( alpha *dB* DELTA nB+ReB)/ lambda B, are matched when thickness of a liquid crystal layer 7 at red, green, and blue dots are dR, dG, and dB; wavelength of a visible light passing each dot is lambda R, lambda R, and lambda B; refractive index anisotropy of the liquid crystal layer 7 in the visible light wavelengths lambda R, lambda R, and lambda B is DELTA nR, DELTA nG, and DELTA nB; and retardations of a retardation plate are ReR, ReG, and ReB. This enables the achievement of a reflective color LCD with high achromatic color during white display and high contrast display.
