TFT (thin film transistor) substrate and manufacturing method thereof

Abstract

The invention discloses a TFT (thin film transistor) substrate and a manufacturing method thereof. The method comprises the following steps of providing a substrate; forming a gate electrode on the substrate; forming a first insulating layer and an active layer in sequence on the gate electrode; forming a first black matrix on the active layer; forming a source electrode and a drain electrode on the first black matrix; forming second insulating layers on the source electrode and the drain electrode; forming pixel electrodes on the second insulating layers, wherein the pixel electrodes are electrically connected with one of the source electrode and the drain electrode through the corresponding second insulating layer. By the mode, the shading effect of a display panel formed by the TFT substrate can be guaranteed; furthermore, coupling capacitance between data lines and scanning lines is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a TFT substrate and a manufacturing method thereof. Background technique [0002] Curved TVs are becoming more and more popular due to their better contrast ratio, wider viewing angles and immersive experience, which provide users with a deeper viewing experience. [0003] In curved TV applications, due to the bending of the panel to a certain extent, there will be a relative misalignment between the TFT (Thin Film Transistor, Thin Film Transistor) substrate and the CF (color filter) substrate that make up the panel, resulting in The light shielding effect of the black matrix (Black Matrix, BM) on the CF substrate is affected. For details, please refer to figure 1 and figure 2 As shown, among them, figure 1 is the shading situation of the black matrix 101 when the panel 100 is not bent, figure 2 After the panel 100 is bent, the shading situation of the black matrix 101 is...

[0003] In curved TV applications, due to the bending of the panel to a certain extent, there will be a relative misalignment between the TFT (Thin Film Transistor, Thin Film Transistor) substrate and the CF (color filter) substrate that make up the panel, resulting in The light shielding effect of the black matrix (Black Matrix, BM) on the CF substrate is affected

For details, please refer to figure 1 and figure 2 As shown, among them, figure 1 is the shading situation of the black matrix 101 when the panel 100 is not bent, figure 2 After the panel 100 is bent, the shading situation of the black matrix 101 is given by figure 1 and figure 2 It can be seen that after the panel 100 is bent, part of the light is emitted from the side of the black matrix 101, resulting in light leakage, affecting the light shielding effect of the black matrix 101, thereby reducing the contrast of the panel
