Abstract

A display device includes an organic layer, an anode, a pixel defining layer, a cathode, a light emitting layer, a light blocking layer, a color filter, and a sensing electrode. The organic layer includes an anode-connecting opening. The anode is disposed on the organic layer and is partially disposed inside the anode-connecting opening. The pixel defining layer includes an anode-exposing opening that exposes the anode. The cathode overlaps the anode. The light emitting layer is between the anode and the cathode. The light blocking layer overlaps the cathode and includes a blocking layer opening. The color filter fills the blocking layer opening. The sensing electrode is at least partially covered by the light blocking layer. The anode-connecting opening overlaps with each of the sensing electrode, the pixel defining layer, and the light blocking layer in a plan view of the display device.
