Abstract
A reflective LCD panel includes a color filter substrate, an array substrate, a liquid crystal layer and a polarizing film. The array substrate and the color filter substrate are disposed oppositely. The liquid crystal layer is disposed between the color filter substrate and the array substrate and has an alignment direction. The polarizing film is disposed on the color filter substrate, and color coordinates of the polarizing film in the CIE1976 color space are (a, b), wherein 0.05≤a≤0.2 and −5≤b≤0. The liquid crystal layer has a birefringence difference Δn, the liquid crystal layer has a thickness (d), when the reflective LCD panel is in a white frame, 2Δn*d=Δλ is satisfied, Δλ is the optical path difference obtained when a forward light vertically enters the liquid crystal layer and is reflected by the array substrate, and 120 nm≤Δn*d≤170 nm.
