Abstract

A liquid crystal display apparatus includes a first spacer, a second spacer which is different in height from the first spacer, and a liquid crystal layer held between an array substrate and a counter substrate. The first spacer is provided at an intersection of a source wiring line and an auxiliary capacitive line, and the second spacer is provided in at least a contact hole.

Claims (7)

1. A liquid crystal display apparatus comprising:

an array substrate comprising (i) a gate wiring line extend g along a first direction, (ii) an auxiliary capacitive line extending along a first direction parallel to the gate wiring line, (iii) a pixel electrode including a belt-shaped primary pixel electrode located along a second direction that intersects with the first direction and a contact portion which is integrally formed with the primary pixel electrode and includes a contact hole located in a region that overlaps the auxiliary capacitive line, and (iv) a source wiring line extending along the second direction parallel to the primary pixel electrode;

a counter substrate comprising a common electrode provided along the second direction in a region facing the source wiring line; and

a first spacer, a second spacer and a liquid crystal layer, which are held between the array substrate and the counter substrate,

wherein the first spacer is provided at an intersection of the source wiring line and the auxiliary capacitive line, and the second spacer is provided in the contact hole,

the contact portion is formed to be greater in width along the first direction than the primary pixel electrode at a region where the primary pixel electrode overlaps the auxiliary capacitive line, and a width along the second direction of the contact portion is smaller than that of the auxiliary capacitive line.

2. The liquid crystal display apparatus according to claim 1 , wherein the counter substrate further comprises an alignment film, and the first spacer is formed on the common electrode and covered with the alignment film.
