Display substrate and display device

Abstract

The invention discloses a display substrate and a display device and relates to the field of display technique. The display substrate and the display device aim at solving the problem that a signal line is not good. The display substrate comprises a substrate body, a first insulation layer, at least one signal line and a second insulation layer, wherein the first insulation layer is arranged on the substrate body and provided with at least one line containing groove; at least one of the signal lines is arranged in the corresponding line containing groove, and each line containing groove is used for containing one signal line; the first insulation layer and the signal lines are covered with the second insulation layer. The display device comprises the display substrate. The display substrate and the display device are used for reducing the probability of the problem that the signal lines are not good.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] With the continuous development of display technologies, thin film transistor (Thin Film Transistor, hereinafter referred to as TFT) liquid crystal displays occupy a dominant position in current displays. The display substrate plays an important role in the high responsivity, high brightness, and high contrast of TFT liquid crystal displays, such as figure 1 As shown, in the prior art, the display substrate 10 includes a base substrate 11 , a signal line 12 disposed on the base substrate, and an insulating layer 13 formed on the signal line. [0003] However, the inventors of the present application found that the existing display substrate 10 has the following defects: since each signal line 12 is arranged on the upper surface of the base substrate 11, the insulating layer 13 formed on the base sub...

Problems solved by technology

[0003] However, the inventors of the present application found that the existing display substrate 10 has the following defects: since each signal line 12 is arranged on the upper surface of the base substrate 11, the insulating layer 13 formed on the base substrate 11 and each signal line 12 There are protrusions; and when an external force acts on the insulating layer 13, the insulating layer 13 is prone to damage, so that the signal line 12 is easily corroded by the electrolyte or water vapor, resulting in a defective signal line.

The alignment film on the display substrate and the position corresponding to the protrusion of the insulating layer 13 form a certain slope, resulting in a rubbing blind area at the position during rubbing alignment, and the blind area causes abnormal alignment of liquid crystal molecules and causes light leakage on the liquid crystal screen
