Abstract

In the forming method of blocking mask and electrode pattern of the prior art, precious metals such as gold and platinum are consumed too much to form metal film on the whole glass substrate, and the manufacturing cost of masks which need to have three manufacturing steps. A blocking mask (6a) and an electrode coating (7c) are formed using a gold film. The blocking mask (6a) and the electrode coating (7c) are formed together by printing an organic gold paste only in a necessary part and baking the printed organic gold paste.

Description

technical field

[0001] The present invention relates to a liquid crystal shutter panel (liquid crystal shutter panel) suitable for a display, a print head, etc., a manufacturing method thereof, and an optical print head using the liquid crystal shutter panel. Background technique

[0002] Figure 7 It is a cross-sectional view showing the general structure of a conventional liquid crystal light gate panel on which a driver IC is mounted. The structure of this liquid crystal control panel is as follows: On the inner surfaces of the upper side glass substrate 1a and the lower side glass substrate 1b which are arranged oppositely, ITO (Indium Tin Oxide: Indium Tin Oxide) covered by the upper side alignment film 2a is respectively formed. The common electrode 3a formed, and the pixel electrode 3b formed by the ITO covered by the lower side alignment film, the liquid crystal cell formed by bonding the upper side glass substrate 1a and the lower side glass substrate 1b with the se...
