Abstract
Projecting sections controlling alignment directions of liquid crystal molecules are provided on at least one of an active matrix substrate and a counter substrate. When viewed from a direction perpendicular to a surface of the active matrix substrate or of the counter substrate, an outline shape of the projecting sections is constituted by continuously arranging a plurality of unit patterns each having a side in parallel with the polarization axis of the first polarizing plate and a side in parallel with the polarization axis of the second polarizing plate. This makes it possible to provide a liquid crystal panel that performs better display with high contrast by reducing a light leakage during a black display period and by ensuring a light transmittance during a gray level display period and a white display period.
