A display apparatus including two lines is provided. The two lines may extend in a first direction. A light-emitting device may be disposed between the two lines. Each line may be bent or extended in the direction of the device substrate which supports the light-emitting device. Thus, in the display apparatus, mixing of light emitted to the outside through the device substrate may be prevented. Therefore, in the display apparatus, the quality of realized image may be improved.
