Abstract
The present application discloses a touch substrate including a base substrate; a transparent touch electrode layer on the base substrate; and an anti-reflective layer on a side of the transparent touch electrode layer distal to the base substrate. The anti-reflective layer includes a first sub-layer on a side of the transparent touch electrode layer distal to the base substrate; a second sub-layer on a side of the first sub-layer distal to the transparent touch electrode layer; and a third sub-layer on a side of the second sub-layer distal to the first sub-layer. The first sub-layer, the second sub-layer, and the third sub-layer are laminated together. The second sub-layer has a refractive index greater than those of the first sub-layer and the third sub-layer.
