A display device is provided, which includes a light sensor in a display panel. The display device comprises a substrate having a unit pixel area and a unit light sensor area, a first electrode over the substrate, a second electrode over the first electrode, a third electrode over the second electrode, a light emitting layer in the unit pixel area and disposed between the first electrode and the second electrode, and a light active layer disposed in the unit light sensor area and disposed between the second electrode and the third electrode.

Display device with more compact light sensor

An organic light emitting display device includes a substrate and a plurality of pixels defined in the substrate. A pixel includes red subpixel, green subpixel, blue subpixel, and white subpixel. The organic light emitting display device includes an anode electrode formed on the substrate, a cathode electrode opposing the anode electrode, and a red common emission layer, a green common emission layer, and a blue common emission layer formed across each of the red, green, blue and white subpixel areas. The blue common emission layer is disposed above and adjacent to the anode electrode, the green common emission layer is disposed above the blue common emission layer, and the red common emission layer is disposed above the green common emission layer and adjacent to the cathode electrode.

Organic light emitting display device and method of manufacturing the same

An organic light emitting display (OLED) device, and a method of manufacturing the OLED device are discussed. The OLED device according to one embodiment includes a substrate; a first pixel electrode, a second pixel electrode, and a third pixel electrode formed on the substrate; a first bank layer and a second bank layer formed on the substrate; and a first organic light emitting layer, a second organic light emitting layer, and a third organic light emitting layer formed on the first pixel electrode, the second pixel electrode, and the third pixel electrode, respectively. The first organic light emitting layer overlaps the second organic light emitting layer on the first bank layer.

Organic light emitting display device and method for manufacturing the same

Provided is an organic light emitting display device. The organic light emitting display device comprises a first substrate, a second substrate facing the first substrate, a transistor on the first substrate, a first contact electrode disposed on the transistor and connected to a source or a drain of the transistor, a subpixel on the second substrate, and a first spacer projected to make an upper electrode included in the subpixel to be in contact with the first contact electrode. An upper surface area of the first spacer is about 0.5% to 20% of an upper surface area of the subpixel.
