摘要： A display device is disclosed. The display device comprises a display panel including a plurality of subpixels; a light emitting diode in a subpixel from the plurality of sub pixels; a first planarization layer that encloses the light emitting diode; a second planarization layer on the first planarization layer and the light emitting diode; and a connection electrode on the second planarization layer and connected to the light emitting diode. The first planarization layer includes a first open area that encloses the light emitting diode and a portion of the first planarization layer corresponding to the first open area has a first thickness that is less than a second thickness of a second portion of the first planarization layer.
