Liquid crystal display device
First Claim
1. A liquid crystal display device comprising:
- a first substrate;
a liquid crystal layer;
a second substrate;
a plurality of pixel regions formed above the second substrate, and each having a pixel electrode; and
first spacers and second spacers both formed on a main surface of the first substrate and arranged between said pixel electrode of neighboring pixel regions and in the liquid crystal layer, wherein when the first spacers are not subjected to an external force and not elastically deformed, each of the second spacers is spaced from a stacked structure formed on the second substrate to accommodate potions of the liquid crystal layer therebetween, and each of the first spacers contacts directly with the stacked structure formed on the second substrate, wherein first portions of the stacked structure contacting with the first spacers are thicker than second portions of the stacked structure corresponding to the second spacers with the portions of the liquid crystal layer interposed therebetween, a distance between said first portions of the stacked structure and the first spacers is longer than a distance between said second portions of the stacked structure and the second spacers, and each of the first spacers and the second spacers has a depression.

Abstract
In order to prevent irreversible deformation of column-shaped spacers which retain the gap between a pair of substrates between which the liquid crystal layer of a liquid crystal display device is interposed, spacers which assist in preventing such irreversible deformation are newly provided. According to the invention, two or more kinds of spacers which differ in height from a reference surface are disposed on one of the pair of substrates. In addition, a step pattern with which the spacers are to come into contact is formed in advance on the other of the pair of substrates so that the heights of the spacers can be made different.

6. A liquid crystal display device comprising:
-
a first substrate including color filters;
a liquid crystal layer;
a second substrate disposed opposite to the first substrate across the liquid crystal layer;
a plurality of first signal lines formed above the second substrate, a plurality of second signal lines intersecting the first signal lines over an insulating film therebetween;
a plurality of pixel regions each formed as being surrounded by respective neighboring first signal lines and second signal lines, and having a pixel electrode;
a base pattern formed between pixel electrodes of neighboring pixel regions;
a plurality of first spacers each formed above a main surface of the first substrate and arranged above a first portion thereof between said pixel electrodes of neighboring pixel regions and overlapping with the base pattern in a plan view; and
a plurality of second spacers each formed above the main surface of the first substrate and arranged above a second portion thereof between said pixel electrodes of neighboring pixel regions and not overlapping with the base pattern in a plan view, wherein when the first spacers are not subjected to an external force and not elastically deformed, each of the second spacers is spaced from a stacked structure formed on the second substrate to accommodate portions of the liquid crystal layer therebetween, and each of the first spacers formed above the base pattern contacts directly with the stacked structure formed on the second substrate, said first portion includes the base pattern, said second portion does not include the base pattern, and said first portion is disposed apart from said second portion across the pixel region, and each of the first spacers and the second spacers has a depression. - View Dependent Claims (7, 8)
