The outer lead area 30 includes an electrical detection area 31, an IC (Integrated Circuit) bonding area 32, and an FPC (Flexible Printed Circuit) bonding area 33, and is used for a module process and related tests.
Since the outer lead area 30 is disposed close to the first edge 11 of the array substrate 01, and each of the bonding areas and the electrical property detection area 31 in the outer lead area 30 extends to another second edge 12 along one second edge 12 of the array substrate 01 perpendicular to the first edge 11, in the prior art, the length of the color filter substrate 02 is designed to be smaller than the length of the array substrate 01 along the direction of the second edge 12, so as to expose the outer lead area 30.
However, due to the market demand for thinning electronic devices, the thickness of the substrate in the display panel gradually changes from 0.2mm to 0.15mm or even 0.1mm, and thus the strength of the substrate is increasingly poor. In the opposite-case portion of the array substrate 01 and the color filter substrate 02, there are a substrate in the array substrate 01 and a substrate in the color filter substrate 02, and only the substrate in the array substrate 01 exists in the outer lead area 30, so that the corner portion where the first edge 11 and the second edge 12 of the array substrate 01 intersect is more easily damaged in the process of drop test and subsequent use, thereby causing damage to electronic equipment.
