[0002]

2. Description of the Related Art In recent years, the development of personal computers,
In particular, with the development of portable personal computers, the demand for color liquid crystal displays tends to increase. However, cost reduction is indispensable for further spread.

Conventionally, as a method of manufacturing a liquid crystal element, a liquid crystal driving element such as a TFT (thin film transistor) or a coloring optical element such as a color filter is provided on a pair of transparent insulating substrates on a glass substrate. After the provision, a transparent electrode and an alignment film are formed. Next, generally, the entire surface of one glass substrate on which the transparent electrode and the alignment film are formed,
True spherical or cylindrical particles of silica, alumina, synthetic resin or the like of about 10 to 10 μm are dispersed as spacers. A liquid crystal element is formed by superposing the pair of glass substrates with the transparent electrodes facing each other via the spacer and sealing the liquid crystal in the gap.

However, in the effective pixel portion (light-transmitting portion), the transmissive / shielded state changes depending on the display state. Therefore, when the spacer is formed of a colorless and transparent material, it becomes a bright point at the time of light-shielding and becomes black. When colored, it is observed as a black spot at the time of transmission, and there is a problem that the display quality is reduced.

In order to solve the above problem, Japanese Patent Application Laid-Open No.
As shown in 173221, JP-A-2-223922, etc., after performing an alignment treatment on an alignment film, a photosensitive polyimide or a photoresist is applied, and exposed through a mask to obtain a polyimide other than an effective pixel portion. And a method of forming a spacer made of resist. According to these methods, a spacer can be formed at an arbitrary density at an arbitrary place, and therefore, the non-uniformity of a liquid crystal cell gap when a liquid crystal is sealed can be improved. Japanese Patent Application Laid-Open No. 3-94230 describes a method of fixing a bead spacer on a light-shielding layer in a region other than an effective pixel portion.

Another method is to use a black matrix having a large thickness as a spacer (Japanese Patent Laid-Open No. 63-23703).
No. 2, JP-A-3-184022, JP-A-4-184
122914), a method of using a colored resist overlapped as a spacer (Japanese Patent Application Laid-Open No. 63-82405), and a method of forming a colored pattern on a black matrix and using it as a spacer (Japanese Patent Application Laid-Open No. 63-237032). ) Has been proposed.

[0007]

The improvement methods proposed in each of the above publications use photolithography, and therefore require an expensive exposure machine, and require the introduction of a wet process such as development. However, there is a problem that the production line becomes longer.

In each of the above-mentioned improvement methods, photosensitive polyimide or photoresist is applied to the entire surface, and unnecessary portions are removed with a solvent or the like after the application, so that there is a problem of contamination of the effective pixel portion. In particular, when a spacer is formed on an alignment film such as a polyimide film that has been subjected to an alignment treatment by a rubbing method or the like, the alignment treatment state applied to the alignment film in the spacer forming process may be significantly contaminated or destroyed. There was a concern that the orientation of the liquid crystal injected into the liquid crystal cell would be non-uniform.

It is desirable that the spacer is securely fixed to at least one substrate surface in order to keep the distance between the substrates (cell gap) constant.

An object of the present invention is to provide a liquid crystal element having a good cell gap holding function, a spacer which does not affect display, and excellent display quality at a lower cost.
