Abstract

A color filter substrate and a display apparatus are provided. The color filter substrate comprises touch sensing units disposed on a black matrix layer, and each of the touch sensing units comprises driving electrodes and sensing electrodes, and the driving electrodes and the sensing electrodes are disposed on the same layer and insulated from each other, and the driving electrodes extend from the driving wire, and the sensing electrodes extend from the sensing wire. At least one wiring unit comprises at least two driving wires and a sensing wire, and each of the driving wires is connected to the driving wire. A multi-touch structure with the monolayer mutual capacitance is achieved for reducing costs, as well as improving yields.
