Embodiment Construction
[0029] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0030] In one embodiment of the present invention, a display substrate is provided.
[0031] The display substrate provided by the present invention includes a display area and a pad area, and both the display area and the pad area are coated with an alignment film material, and at least one lead is arranged on the pad area.
[0032] Figure 4 A schematic structural diagram of an existing lead wire is shown. Such as Figure 4 As shown, the existing lead wire 40 has a flat structure. When the alignment film 20 is coated on the lead wire 40, the alignment film 20 covers the lead wire 40 as a whole. Since the alignment film is an insulating film, the lead w...

Abstract
The invention provides a display substrate. The display substrate is characterized by comprising a display area and a bonding pad area, wherein the display area and the bonding pad area are coated with alignment film materials respectively, at least one lead is arranged on the bonding pad area, the surface of each lead comprises a concave-convex structure, the convex portion in the concave-convex structure is not covered with the alignment film materials and can make conductive contact with a chip on a film, and the concave portion in each concave-convex structure contains the alignment film materials. Due to the fact that the leads of the bonding pad area of the display substrate are arranged to be of the concave-convex structures, when alignment film coating is performed, the whole substrate can be coated with the alignment film materials, and a Halo area is prevented from being generated at the edge of the alignment film on the obtained display substrate.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display device and a manufacturing method thereof. Background technique [0002] In the display industry, especially the TFT-LCD manufacturing industry, with the expansion of the industry line, inkjet printing is usually used for the coating of the alignment film. This printing method requires the viscosity of the alignment film to be low, usually less than 15cp. [0003] Since the alignment film is coated on the substrate in a liquid state, during the evaporation process of the solvent of the alignment film, the evaporation speed of the solvent at the edge of the alignment film is faster at the periphery of the alignment film pattern, and at the same time, due to the surface tension of the solvent of the alignment film, the solute continuously flows to the most The edges accumulate, and the thickness of the alignment film at the edge is thicker, a...
