Problems solved by technology

[0004] The above-mentioned gap depends on the height of the columnar spacers supporting the pair of substrates, and it is known that if there is a deviation in this height, it will directly lead to a deviation in the gap and deteriorate the display quality.

other Embodiment approach

[0096] In the present invention, the following configurations can also be employed in the above-described embodiments.

[0097] That is, in the above-mentioned embodiment, the plurality of protrusions provided on the prismatic spacer 4 are two hemispherical bodies 6 , but the number is not limited. In addition, if Figure 8 As shown, the plurality of protrusions can also be, for example, four quadrangular pyramids 106, and can also be as Figure 9Four triangular pyramids 206 are shown. In the case where a plurality of protrusions are made into pyramids such as quadrangular pyramids 106, triangular pyramids 206, and cones, since the front ends are sharper than those of hemispheres 6 or cylinders, it is possible to obtain the best shape that is easy to deform under a small force. Good height adjustment part5. In any shape, the height of the protrusion is greater than 0 and less than or equal to 1.0 μm, and the width is greater than 0 and less than or equal to 1 / 2 of the front...

Abstract

Provided is a liquid crystal display element which is capable of preventing an irregular display by maintaining a constant gap between a pair of substrates by a simple structure. A plurality of post-like spacers (4) are provided on a color filter substrate (2) in a liquid crystal display element (1) to maintain a constant gap (G) between the substrates. The post-like spacers (4) are provided, at their tips abutting on the other array substrate (3), with height adjusters (5) which are more deformable than non-tip portions when the pair of substrates (2, 3) are adhered to each other.

Description

technical field [0001] The present invention relates to a liquid crystal display element including a plurality of columnar spacers for maintaining a uniform gap between the pair of substrates on any one of a pair of substrates, and a method for manufacturing the same. Background technique [0002] Conventionally, in a liquid crystal display element, a pair of glass substrates are bonded together with a gap kept constant, a liquid crystal material is filled therebetween, and a display function is realized by applying an electric signal to the liquid crystal material. In order to keep the gap constant, a method of using a gap material such as plastic beads is known. [0003] In recent years, columnar spacers are used instead of this gap material. The columnar spacer is also called a photospacer, is known to be formed to overlap the colored layer, and is formed of a dedicated material such as photosensitive polyimide, photosensitive acrylic resin, photosensitive colored resin,...
