Display device having touch sensor and black matrix on the encapsulation unit

Last updated:

Abstract:

A display device having touch sensors is discussed, which can achieve process simplification and cost reduction. In the display device, a black matrix including first and second black layers is arranged on an encapsulation unit arranged to cover light emitting elements, the first black layer is conductively connected to a plurality of touch electrodes and is arranged between color filters overlapping the touch electrodes, and the second black layer is arranged on a different plane from the first black layer and is arranged between color filters not overlapping the touch electrodes. Thereby, the first black layer can be used not only as the black matrix but also as the touch electrodes and thus light leakage can be prevented and an aperture ratio can be improved, and the touch sensors are arranged on the encapsulation unit without a separate attachment process and thus process simplification and cost reduction can be achieved.
