Abstract:
A reflective LCD device includes a reflective film having a convex and concave pattern, wherein the convex and concave pattern includes a plurality of pattern groups having a common pattern and each including a plurality of (N) figure elements. Each figure element is obtained by randomizing a corresponding figure element in a standard pattern including a plurality of standard figure elements. In the randomization, the discrete angle of bright spots generated by diffraction of the reflected incident light assumes 0.01 degrees or smaller. The discrete angle α of the bright spots is defined by: α=(λA/Ls×N)·(180/π) where λA and Ls are average wavelength of the incident light and pitch of the standard pattern, respectively.
