Display panel, display device, and method for manufacturing display panel

Abstract

The present disclosure relates to a display panel, a display device, and a method for manufacturing a display panel. The display panel has an electrode region, the electrode region including a substrate, a data line layer, and an isolation layer which are provided on the substrate and alternated in a direction parallel to an upper surface of the substrate, wherein the height of the data line layer is equal to the height of the isolation layer. Since there is no height difference between the data line layer and the spacer layer and there is no groove, the possibility that conductive foreign objects are accumulated at the isolation layer at this time is greatly reduced, the smooth surface is more conducive to the movement of foreign objects, and a cleaning tape can remove the foreign objects.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application is a National Stage Entry of PCT / CN2016 / 084243 filed on Jun. 1, 2016, which claims the benefit and priority of Chinese Patent Application No. 201610117900.3 filed on Mar. 2, 2016, the disclosures of which are incorporated herein in their entirety as a part of the present application.BACKGROUND[0002]The present disclosure relates to the technical field of display, and in particular, to a display panel, a display device, and a method for manufacturing a display panel.[0003]There are generally four processes to produce a liquid crystal panel: array process, color filter (CF) process, cell process, and module process. The coating of electrode region (Pad) is completed in the array process, and the attaching of COF and PCB is completed in the module process. Before the attaching process in the module process is performed, the electrode region is pressure-cleaned using a cleaning tape.[0004]Under existing technical condi...

AI Technical Summary

Benefits of technology

The present disclosure provides a display panel, display device, and manufacturing method that solves the problem of easily short-circuited data lines and high NG rates in conventional display technology. The display panel has a substrate in the electrode region with alternating data line layers and isolation layers, which prevents short circuits caused by tilting of data lines, reduces equipment and personnel costs, and improves product yield.

Problems solved by technology

First, since a data line layer is higher than an adjacent insulating layer, foreign objects are accumulated in the insulating layer when the electrode region is cleaned, and when foreign objects too many are accumulated, a short circuit is caused among the data lines.

Second, since the data line layer is higher than the adjacent insulating layer, the data lines might be caused to tilt toward the insulating layer due to pressure reason or loose array coating during the cleaning of the electrode region, and when too many foreign objects are accumulated, a short circuit is caused between the data lines.
