Abstract
A touch screen comprises a glass substrate, a first conductive layer, an insulating adhesive layer and a second conductive layer. The first conductive layer is directly formed on the glass substrate and comprises first conductive pattern areas; the insulating adhesive layer is attached to the glass substrate, and one side of the insulating adhesive layer close to the glass substrate forms a first groove; the first conductive pattern area is received in the first groove and insulated from each other; one side of the insulating adhesive layer away from the glass substrate, is provided with a second groove; and the second conductive layer is received in the second groove, thus forming a plurality of second conductive pattern areas insulated with each other. The first conductive layer is directly formed on the glass substrate and made of a metal material, thus omitting an adhesive layer and saving the cost.
