Display substrate and manufacturing method thereof, touch panel, and display device

摘要

The present invention provides a display substrate and a manufacturing method thereof, a touch panel comprising the display substrate, and a display device. The display substrate comprises: a first substrate; a thin film transistor, a first electrode and a second electrode formed on one side of the first substrate; and a black matrix and a color filter layer formed on the other side of the first substrate, wherein at least one of the black matrix and the color filter layer is made of conductive material, a display electric field is formed between the first electrode and the second electrode, and a touch-control electric field is formed between the first electrode and the black matrix and/or the color filter layer. The solution of the invention can improve accuracy of determination of location where touch occurs and display quality, and reduce thickness of the display substrate.

主权项

1. A display substrate, characterized by comprising:
a first substrate comprising a first side and a second side opposite to the first side; a thin film transistor disposed directly on the first side of the first substrate; a first electrode disposed directly on the thin film transistor; a second electrode disposed on the first electrode; and a black matrix and a color filter layer disposed in a same layer on the second side of the first substrate, wherein at least one of the black matrix and the color filter layer is made of conductive material, a display electric field is formed between the first electrode and the second electrode, and a touch-control electric field is formed between the first electrode and the black matrix and/or the color filter layer.
