摘要： A display device includes a substrate including a display region including a plurality of pixels and a non-display region at one side of the display region; at least one transistor on the substrate; a light emitting element connected to the transistor; a thin film encapsulation layer covering the light emitting element; a plurality of light blocking patterns on the thin film encapsulation layer, the plurality of light blocking patterns corresponding to at least a portion of a non-emission region of each pixel, and a planarization layer covering the light blocking patterns; and a touch sensor including a plurality of touch electrodes on the planarization layer. None of the light blocking patterns overlap touch electrodes.
