Abstract

The invention provides a display panel and a manufacturing method thereof, and the method comprises the steps: sequentially carrying out the conductor processing of a first electrode and an oxide semiconductor layer, which are made of the same metal oxide semiconductor material; a first electrode made of a metal oxide semiconductor material can be made into a conductor without a gate insulating layer and a gate metal layer above the metal oxide semiconductor material, so that a storage capacitor can be formed by using the conductor oxide semiconductor layer and the gate metal layer above the conductor oxide semiconductor layer; therefore, the capacitance value of the storage capacitor can be increased, and the problem of poor display caused by insufficient capacitance value of the storage capacitor is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a manufacturing method of the display panel. Background technique [0002] When an active-matrix organic light-emitting diode (AMOLED) display is turned on, after writing a data signal in each sub-pixel, the data signal voltage needs to be maintained before the next frame scan, which requires each sub-pixel There is enough capacitance inside the pixel drive circuit. Otherwise, problems such as screen flickering and bright / dark spots will occur. [0003] The capacitance value of the capacitor is proportional to the capacitance area. In order to have enough capacitance, the capacitance area needs to meet the corresponding capacitance value requirements. In fact, in the array drive circuit of AMOLED products, the capacitor occupies a large area in the drive circuit, which is an important difficulty in the process of improving the resolution (pix...
