Abstract

The invention provides a display panel. The display panel comprises a grid driver, multiple scanning lines and multiple thin film transistors. The scanning lines are connected with the grid driver, and the thin film transistors are connected to the scanning lines respectively. The grid of each thin film transistor is connected with the corresponding scanning line. The drain electrodes of the thin film transistors are provided with overlapping portions overlapped with the grids in the vertical direction. The area of the overlapping portions in the horizontal direction is evenly and gradually increased from the position close the grid driver to the position far away from the grid driver. According to the display panel, the area of the overlapping portions, overlapped with the grids, of the drain electrodes is changed by changing the area of the drain electrodes of the thin film transistors in the horizontal direction so as to evenly compensate for signal waveforms of pixel units, and accordingly the image display quality of the display panel is improved.

Description

technical field [0001] The invention relates to a display panel, in particular to a liquid crystal display panel. Background technique [0002] With the continuous development of technology and continuous improvement of technology, display panels have been widely used in people's daily life and production, especially liquid crystal display panels, which are widely used in various portable electronic products, transportation tools, etc. [0003] A liquid crystal display panel usually includes a gate driver, a source driver and a pixel unit, and the pixel unit is connected to the gate driver and the source driver through a scan line and a data line respectively. However, the signal will be attenuated during the transmission process, especially in a larger-sized display panel, the signal waveform attenuation of the pixel unit farther away from the gate driver is more obvious, which seriously affects the display effect of the display panel.
