Abstract: A display device includes: a semiconductor layer including source (SR), drain (DR), and channel (CR) regions; a first insulating layer (FIL) on the semiconductor layer; a gate line on the FIL and overlapping the CR; a second insulating layer (SIL) on the gate line; a first contact hole (FCH) in the FIL and the SIL, and exposing the SR; a data line on the SIL and contacting the SR; a third insulating layer (TIL) on the data line; a second contact hole (SCH) in the first to third insulating layers and exposing the DR; a drain electrode on the TIL and contacting the DR; a color filter on the TIL and not overlapping the SCH; a pixel electrode (PE) on the color filter and contacting the drain electrode; and an organic layer on the TIL and the PE. Upper surfaces of the organic layer and the PE are substantially coplanar.

Abstract: A light emitting device includes a first electrode, an insulating layer, a second electrode, and a bar-type light emitting diode (LED). The insulating layer includes a plurality of protruding parts protruding from the first electrode and at least one hole between the protruding parts. The second electrode on the insulating layer. The bar-type LED is in the at least one hole. The bar-type LED has a first end and a second end in the length direction. One of the first or second ends is connected to the first electrode and the other of the first or second ends is connected to the second electrode.
