Abstract
A liquid crystal panel includes an array substrate, a counter substrate, and a liquid crystal layer therebetween. The counter substrate includes a sub-pixel in-between light blocking section extending in a grid and surrounding the sub pixels, a first projection projecting from the counter substrate toward the array substrate and having a projecting end that is contacted with a part of the array substrate to define a distance between the substrates, and second projections projecting from the counter substrate toward the array substrate and having projecting ends that are spaced from the array substrate. The first projection and the second projections overlap the sub-pixel in-between light blocking section. A distance between a center line of a width dimension of the sub-pixel in-between light blocking section and a center of each second projection is smaller than a distance between the center line and a center of the first projection.
