Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology, and adjust the quantity and arrangement of electrostatic protection circuits to better adapt to a narrow-frame display panel. The display panel includes a display area and a non-display area, the non-display area includes an upper side and a lower side non-display area arranged along the first direction, and the lower side non-display area is provided with a driver chip; a data line; a gate circuit, a gate circuit Located on the side of the driver chip near the display area in the non-display area on the lower side, the gate circuit is connected to the data signal input wiring and at least two data lines, and the data signal input wiring is connected to the driver chip; electrostatic protection circuit, electrostatic protection The circuit is arranged between the drive chip and the gate circuit; the electrostatic protection circuit includes a first diode and a second diode, and the first diode and the second diode are connected to the data signal input wiring, and the first and second diodes The pole transistors and the second diodes are arranged along the second direction. The above-mentioned display panel is used to realize screen display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] The display panel includes a display area and a non-display area, and a plurality of data lines are arranged in the display area. During the production process of the display panel, due to some external factors, a large amount of static charge will be accumulated in the display panel, thereby causing electrostatic discharge. During electrostatic discharge, the electrostatic charge will be transferred in a short time, resulting in extremely high electrostatic current, which will affect the data signal transmitted on the data line. In order to overcome the above problems, a plurality of electrostatic protection circuits are provided in the non-display area of ​​the display panel. [0003] In the prior art, the ESD protection circuit is usually arranged in the lower non-display area, and one data line...
