Abstract

PURPOSE:To obviate the generation of a difference in the space between glass substrates between a part where pastes are close and the parts where the pastes are not close by forming part where the pastes are close to the paste diameter smaller than the paste diameter of the part where the pastes are not close. CONSTITUTION:The conductive pastes 9, 10 for transferring electrode terminals for impressing a voltage to upper electrodes 2-5 to terminals 7 for voltage impression on a lower substrate 6. are disposed between an upper and lower electrodes 1, 6. The good result is obtd. by setting the diameter of the conductive paste 10 at the diameter smaller than the diameter of the conductive paste 9 if the conductive paste 10 is more closely distributed than the conductive paste 9. The diameter of the conductive paste in the place where the conductive pastes are closely distributed is usually set in the 50-90% range of the diameter of the conductive paste in the place where the conductive pastes are not closely distributed so that the total cross sectional areas of the conductive pastes in both places are set approximately equal. The most adequate result is then obtd. The space between the substrates of the liquid crystal display element is thereby uniformized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid crystal display element, and particularly to a liquid crystal display element with good uniformity in the distance between two upper and lower glass substrates.

[Conventional technology]

Electrode terminals for applying voltage to pattern electrodes formed on the inner surfaces of opposing glass substrates of liquid crystal display elements have been moved to only one substrate to facilitate connection with external circuits. . this is.

This is done by interposing a conductive paste between at least a portion of opposing electrodes to electrically short-circuit these electrodes (Utility Model Publication No. 59-5851, Japanese Patent Publication No. 60-11331, (Japanese Utility Model Publication No. 60-20103 and Japanese Patent Publication No. 56-36537), the short-circuit connection between electrodes for this purpose is hereinafter referred to as an up-down connection.

[Problem that the invention seeks to solve]

In the above-mentioned conventional example, even if there are a plurality of upper and lower connection points, all the paste diameters are approximately the same, so the gap between the substrates in the part where the paste is densely packed becomes uneven, resulting in color unevenness.

This is because when the diameter of the paste is the same, the paste in the densely packed portions will not be crushed and the intervals will be large.

An object of the present invention is to prevent a difference in the distance between the glass cancer plates between a part where the paste is not densely packed and a part where the paste is densely packed.

[Means for solving problems]

The above problem can be solved by making the paste diameter in the part where the paste is densely packed smaller than the paste diameter in the part where the paste is not densely packed.

[Effect]

By making the paste diameter in the part where the paste is densely packed smaller than the paste diameter in the part where the paste is not densely packed, the total paste area in both places becomes almost the same, so the pressure is applied equally between the boards. Therefore, the spacing between the substrates is uniform, and color unevenness does not occur.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the inner surface of the upper substrate 1 has an upper electrode 2°3.4
and 5 are formed on the inner surface of the lower substrate 6, pattern electrodes (not shown) corresponding to the upper electrodes 2, 3, 4, and 5 and shaped in accordance with the content to be displayed are formed, and Among the sides of the lower board 6.

A voltage application terminal 7 is formed on the side protruding from the upper substrate 1. The upper and lower substrates 1 and 6 are spaced at a predetermined interval (usually 5
~10μ) and is fixed with a frame-shaped sealant 8. Between the upper and lower substrates 1 and 6 are conductive pastes 9 and 10 for transferring the electrode terminals for applying voltage to the upper electrodes 2, 3 and 4.5 to the voltage application terminals 7 on the lower substrate 6. is installed.

In FIG. 1, the distribution of conductive paste 10 is denser than the distribution of conductive paste 9. In this embodiment, the diameter of the conductive paste 10 is set to 7 of the diameter of the conductive paste 9.
Good results were obtained by setting the conductive paste to 5%.1 Normally, the diameter of the conductive paste in areas with a high concentration of conductive paste is set within the range of 50 to 90% of the diameter of the conductive paste in a non-concentrated area. Most preferably, the total cross-sectional area of the conductive paste at each location is approximately equal.

〔Effect of the invention〕

According to the present invention, since the spacing between the liquid crystal display element substrates can be made uniform, color unevenness can be effectively prevented.
