Abstract:
The liquid crystal display panel includes: a first polarizing plate; a first λ/4 plate; a first substrate; a second λ/4 plate; a liquid crystal layer; a second substrate; and a second polarizing plate, wherein the first substrate includes a black matrix but no photo spacer, the second substrate includes a photo spacer overlapping with the black matrix, liquid crystal molecules in the liquid crystal layer homogeneously align with no voltage application, the second λ/4 plate covers no side surface of the photo spacer, and the in-plane slow axis of the first λ/4 plate forms an angle of 45° with the transmission axis of the first polarizing plate and is orthogonal to the in-plane slow axis of the second λ/4 plate.
