Manufacturing method for display panel

Abstract

The embodiment of the invention discloses a manufacturing method for a display panel. The method comprises the following steps that a substrate is provided, and at least one exposure alignment identification is arranged on the substrate; a colorful filter layer is formed at one side, away from the substrate, of the at least one exposure alignment identification, the colorful filter layer comprisesan identification thickening layer covering the exposure alignment identification, and shapes and sizes of the identification thickening layer and exposure alignment identification are same; a blacklight resistance layer is formed at one side, away from the substrate, of the colorful filter layer; exposure alignment is conducted by utilizing the exposure alignment identification and the identification thickening layer so as to carry out exposure on the black light resistance layer, and a block light shading layer is formed. According to the provided manufacturing method for the display panel, the identification thickening layer covering the exposure alignment identification is formed to increase the height of the position of the exposure alignment identification, and after the subsequentblack light resistance layer is formed, the exposure alignment identification can be accurately identified, therefore the manufacturing accuracy of the black shading layer is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a method for manufacturing a display panel. Background technique [0002] With the development of display technology, in order to avoid the mismatch of light-shielding areas caused by the dislocation of the upper and lower substrates, the black matrix is ​​usually integrated on the array substrate, that is, BOA (Black Matrix on Array) technology. At the same time, in the manufacturing process of the display device, in order to improve the alignment accuracy in the manufacturing process, an exposure alignment mark is usually provided. [0003] However, due to the high optical density (optical density, OD) of the black light-shielding layer material forming the black matrix, after the black light-shielding material is coated, it will interfere with the recognition of the mask exposure alignment mark, which will cause the exposure machine to fail. Precise alignment;...

[0003] However, due to the high optical density (optical density, OD) of the black light-shielding layer material forming the black matrix, after the black light-shielding material is coated, it will interfere with the recognition of the mask exposure alignment mark, which will cause the exposure machine to fail. Precise alignment; if a black light-shielding layer material with a low optical density value is used, although it can reduce the difficulty of identifying the mark, it will seriously affect the light-shielding effect of the black matrix
