晶表示パネルに関するものでおる。DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to the structure of a liquid crystal display pile, and in particular to the formation of an insulating film having an appropriate light transmittance in a display area other than the area that lights up when a voltage is applied. The present invention relates to a liquid crystal display panel that makes it easier to see displayed characters.

成され、電極２はｙ方向に伸びて形成されている。BACKGROUND OF THE INVENTION Conventionally, liquid crystal display panels in which liquid crystal is sealed between two glass substrates facing each other with a predetermined gap in between have been widely used. In this case, electrodes as illustrated in FIG. 1 are formed on opposing surfaces of each glass substrate. In the figure, 1 is a plurality of electrodes formed on one glass substrate, and 2 is a plurality of electrodes formed on the other glass substrate. Electrode 1 is y
The electrodes 2 are formed to extend in two directions perpendicular to one direction at equal intervals in the direction, and the electrodes 2 are formed to extend in the y direction.

まい、その結果、表示文字が見にくくなっていた。However, in this case, voltage is also applied to the non-selected point 4 (indicated by an x mark in the figure) in the literary part of electrodes 1 and 2 other than characters, and this part is where electrodes 1 and 2 intersect. It appears to be lit compared to the non-display area 5, which is a blank area. In other words, the entire character display section appears to be lit, making it difficult to see the displayed characters.

プ、印刷→焼成によって形成されるイミド樹脂。FIG. 2 is a plan view showing a part of one of the glass substrates 11 to which the present invention is applied, and members having the same configuration as the conventional one are indicated by the same symbols as the conventional one. An insulating film 13 having an appropriate light transmittance is formed in a portion of the display area 12 of the glass substrate 11 other than the character display portion (hatched portion in the figure). FIG. 6 shows only the insulating film 16 formed on the glass substrate 11, and 14 is a character display section. This insulating film 13 has 5
10W, Ta205, and other inorganic materials can be used to form a thin film, and its light transmittance can be controlled by appropriately setting the ratio of Si to O and the ratio of Ta to O. . Further, the insulating film 13 is an imide resin formed by spin cord, tip, printing and then firing.
シリコン樹脂等の有機フィルムによっても実現できる。It can also be realized using an organic film such as silicone resin.
要は液晶材料に対し化学的に安定なものであれば良い。In short, any material that is chemically stable to the liquid crystal material is sufficient.

た。A liquid crystal display is obtained by forming a molecular alignment film on this insulating film 13 and laminating it with another glass substrate on which a molecular alignment film is similarly formed on the electrode to form a cell, and enclosing a liquid crystal inside the cell. A front sectional view of the panel is shown in FIG. In the figure, 15 is the other glass substrate, 16 and 17 are molecular alignment films, and 18 is a liquid crystal. In this case, when the light transmittance of the insulating film 16 is set to 50 to 90 inches, the display area other than the character display part 14 (the part where the insulating film 16 is formed) has the same brightness as the non-selected points in the character display part 14. It was confirmed that the displayed characters became easier to read.

By setting the brightness appropriately, the brightness of the insulating film forming portion can be made comparable to that of the non-selected points in the full character display area. Therefore, it is possible to improve the display quality by making the displayed characters easier to see.
