Abstract: A display device is capable of improving transmittance and side visibility, the display device including: a substrate; a thin film transistor disposed on the substrate; and a pixel electrode disposed on the thin film transistor and comprising a first sub-pixel electrode and a second sub-pixel electrode connected to the first sub-pixel electrode. The first sub-pixel electrode includes a plurality of first branch portions. The second sub-pixel electrode includes a plurality of second branch portions. The plurality of second branch portions are arranged at a pitch substantially equal to a pitch of the plurality of first branch portions. An interval between the plurality of second branch portions is greater than an interval between the plurality of first branch portions.

Abstract: A pixel of a light emitting display device includes: a switching transistor which transfers a data voltage in response to a gate writing signal, a storage capacitor which stores a storage voltage, a driving transistor which generates a driving current based on the storage voltage stored in the storage capacitor, an emission transistor which selectively forms a path of the driving current in response to an emission signal, a light emitting diode which emits light based on the driving current, and a diode initialization transistor which transfers an initialization voltage to the light emitting diode in response to the emission signal. The storage voltage corresponds to a value obtained by subtracting a threshold voltage of the driving transistor from the data voltage.

Abstract: A display apparatus includes: a first pixel, a second pixel, and a third pixel respectively configured to emit different colors; a first partition wall on a first light-emitting device of the first pixel; and a first color conversion layer corresponding to an emission area of the first pixel. The first partition wall has a first opening corresponding to the first light-emitting device and a first concave portion spaced apart from the first opening in a plan view. The first color conversion layer includes first quantum dots configured to convert incident light into first color light.
