Display substrate, manufacturing method thereof and display device

Abstract

The invention discloses a display substrate, a manufacturing method thereof and a display device. The display substrate comprises a base, and a semiconductor layer, a first metal layer, a second metallayer, a third metal layer, a fourth metal layer and a fifth metal layer which are sequentially arranged on the base and are insulated from one another, wherein the semiconductor layer comprises active layers of a plurality of transistors, the first metal layer comprises a grid line, a light-emitting control line, a reset signal line, a first electrode of a storage capacitor and grid electrodes of the plurality of transistors, and the second metal layer comprises an initial signal line and a second electrode of the storage capacitor; the third metal layer includes source and drain electrodesof the plurality of transistors, the fourth metal layer includes a data line and a power line, and the fifth metal layer includes an anode of the light emitting device. According to the OLED display substrate, the data lines, the power lines and the source and drain electrodes of the plurality of transistors are arranged on different layers, so that the volume occupied by the sub-pixels and the data lines connected with the sub-pixels can be reduced, and the resolution of the high-frequency driven OLED display substrate is further improved.

Description

technical field [0001] This article relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Device, referred to as OLED) display substrate is a display substrate different from traditional liquid crystal display (Liquid Crystal Display, referred to as LCD), with active light, good temperature characteristics, low power consumption, responsive Fast, bendable, ultra-thin and low cost. Therefore, it has become one of the important development discoveries of the new generation display device, and has received more and more attention. [0003] In order to realize the high-frequency driving of the OLED display substrate, an OLED display substrate with double data lines is proposed in the related art, that is, pixels in the same row are connected to two data lines. However, although the OLED display substrate in the rel...
