Abstract

The embodiment of the invention provides a display panel and a display device, which relate to the technical field of display and reduce the coupling capacitance of a gate electrode of a driving transistor and a data line. The display panel includes a pixel circuit including a driving transistor; a first switching transistor having a first pole connected to a reference voltage signal line and a second pole connected to a gate of the driving transistor; a second switching transistor having a first pole connected to the data line and a second pole connected to the first pole of the driving transistor; a third switching transistor having a first pole connected to the power supply voltage signal line and a second pole connected to the first pole of the driving transistor; the display panel further includes a shielding unit for receiving a fixed potential signal, at least a part of the shield unit is located between the first semiconductor connection part and the second semiconductor connection part, the first semiconductor connection part is connected between the second pole of the first switching transistor and the gate of the driving transistor, and the second semiconductor connection part is connected between the first pole of the second switching transistor and the data line.

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] With the continuous development of display technology, organic light-emitting display panels are more and more widely used due to their excellent characteristics such as self-illumination, high brightness, wide viewing angle, and fast response. However, in recent years, with the continuous improvement of resolution, the gap between metal film layers used to form signal lines and transistors in organic light-emitting display panels has become very small, which makes large gaps between metal film layers. The coupling effect forms a coupling capacitance, which affects the luminance of the light-emitting element and affects the display performance. 【Content of invention】 [0003] In view of this, an embodiment of the present invention provides a display panel and a display device, which are used to re...
