Title:

DISPLAY SUBSTRATE AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/004539

Kind Code:

A1

Abstract:

A display substrate (10) and a display device. The display substrate (10) comprises a base substrate, crack detection lines (21), and electrostatic discharge elements (211) electrically connected to the crack detection lines (21). The base substrate comprises a main body region (11), an auxiliary region (13), and a neck region (12) connecting the main body region (11) and the auxiliary region (13). A display region of the display substrate (10) is located in the main body region (11). Each of the crack detection lines (21) extends at least partially around the display region and through the neck region (12) to the auxiliary region (13). The length direction of the neck region (13) is parallel to a first direction (D1). The main body region (11), the neck region (12), and the auxiliary region (13) are connected in a second direction (D2). The first direction (D1) intersects the second direction (D2). The maximum size of the neck region (12) in the first direction (D1) is smaller than the maximum size of the main body region (11) in the first direction (D1) and the maximum size of the auxiliary region (13) in the first direction (D1). The electrostatic discharge elements (211) are located in the auxiliary region (13). According to the display substrate (10), it is beneficial to improving the detection rate and yield of the display substrate (10).
