Abstract

The invention belongs to the technical field of display, and particularly relates to a display panel, a manufacturing method thereof and a display device. The display panel comprises a first substrate and is divided into a display area and a non-display area, and the non-display area of the first substrate comprises an IC attaching area. The manufacturing method includes the step of thinning. The manufacturing method is characterized in that the step of thinning includes: 1), forming a barrier layer insoluble in thinning liquid in an area, corresponding to the IC attaching area, of the first surface of the first substrate of the display panel; 2), adopting the thinning liquid to thin the display panel to enable thickness of the IC attaching area of the first substrate to be larger than that of the display area; 3), removing the barrier layer. Zones, different in thickness, of the display panel are formed through local thinning, suitability of attaching of a driving IC is realized while strength of the display panel is guaranteed, and thinning of the display panel is realized; thickness of the display area of the display panel is guaranteed, so that light leakage and bad COG Mura effect are avoided.

Description

technical field

[0001] The invention belongs to the field of display technology, and in particular relates to a method for preparing a display panel, a display panel, and a display device. Background technique

[0002] The liquid crystal display panel includes a display panel cell, a printed circuit board PCB, a driver IC, etc., where the cell and the driver IC are generally connected by means of COG (Chip On Glass) through ACF (Anisotropic Conductive Adhesive), and the PCB and the cell are connected through a flexible circuit board. FPC connection.

[0003] Now, small-sized liquid crystal display panels are more and more inclined to be ultra-thin and ultra-high-resolution in the market. Along with users' requirements for product quality, designers' demands for panel edge area, and manufacturers' cost control, driving The IC is developing towards multi-pin and narrow and long, and the length of the driving IC is increased to meet the resolution requirements; while the liqui...
