Component Substrate And Alignment Method

Abstract

A component substrate includes a substrate having an active zone and a peripheral zone, a pixel array disposed in the active zone, a plurality of signal connecting pads disposed on the substrate and connected with the pixel array electrically and at least one testing connecting pad disposed in the peripheral zone and connected with the pixel array electrically. The testing connection pad includes a conducting layer disposed in the peripheral zone, an insulation layer covering the conducting layer and a contact pattern layer disposed on the insulation layer. The insulation layer has at least one contact opening and at least one groove. The conducting layer is exposed from the contact opening. The contact pattern layer is connected with the conducting layer electrically through the contact opening. A part of the contact pattern layer is disposed in the groove. Besides, the alignment method for the above component substrate is also disclosed. The alignment films on different areas on the substrate can have approximate anchoring forces, so that a problem of poor alignment in the prior art can be solved.

Description

technical field [0001] The present invention relates to a substrate and its alignment method, and in particular to an element substrate and its alignment method. Background technique [0002] The display panel includes an element substrate, an opposite substrate opposite to the element substrate, and a display medium arranged between the element substrate and the opposite substrate. Taking a liquid crystal display panel as an example, the display medium is a plurality of liquid crystal molecules. When the display panel is enabled, in order to enable the optical axis of the liquid crystal molecules to turn to the specified direction correctly and quickly, so as to provide the specified transmittance of the corresponding pixel, an alignment film is usually provided on the component substrate. Through the anchoring force provided by the alignment film, the optical axes of multiple liquid crystal molecules can be tilted in a specified direction when the display panel is not ena...

AI Technical Summary

Problems solved by technology

When using an alignment tool to carry out a contact alignment process on the alignment film, the amount of downward force of the alignment tool on the alignment film will be affected by the height difference between the test pad and the surrounding film layer, resulting in active components on the component substrate. The anchoring force of the alignment film near the junction of the region and the peripheral region and the center of the active region is inconsistent, that is, the problem of rubbing mura
