Problems solved by technology

[0003] However, when IGZO is used to make the active layer in a thin film transistor, because IGZO is easily affected by external light, such as figure 1 As shown, it will make the active layer unstable, resulting in unstable performance of thin film transistors in the presence of external light

Abstract

The present invention relates to a display substrate and a manufacturing method thereof, and a display apparatus. The display substrate comprises: a thin film transistor which is provided with an active layer therein; and a light shield layer which is arranged over the active layer and is used for shielding lights irradiating towards the active layer. According to the technical scheme of the present invention, the light shield layer is arranged over the active layer, so that external lights can be effectively prevented from irradiating to the active layer in the thin film transistor, thereby avoiding unstable performance of the thin film transistor caused by influence on the active layer from the outside illumination.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display substrate, a display device and a method for manufacturing a display substrate. Background technique [0002] IGZO is an oxide containing indium, gallium and zinc. The carrier mobility is 20 to 30 times that of amorphous silicon. It is used to make the active layer of TFT (thin film transistor) can greatly improve the TFT to the pixel electrode. The charge and discharge rate improves the response speed of the pixel and achieves a faster refresh rate. At the same time, the faster response also greatly improves the row scanning rate of the pixel, making ultra-high resolution possible in TFT-LCD. In addition, IGZO displays have higher energy efficiency levels and are more efficient due to the reduced number of transistors and increased light transmittance per pixel. [0003] However, when IGZO is used to make the active layer in a thin film transistor, because I...
