Abstract: A display device includes a display area where an image is displayed, a non-display area disposed adjacent to the display area, a first sub-pixel disposed in the display area, and a second sub-pixel disposed adjacent to the first sub-pixel in the display area. Each of the first sub-pixel and the second sub-pixel includes a plurality of alignment electrodes spaced apart from each other, and a plurality of light emitting elements disposed between the plurality of alignment electrodes. Each of the plurality of light emitting elements includes a first end having a first polarity, and a second end having a second polarity different from the first polarity. An orientation of the light emitting elements in the first sub-pixel and an orientation of the light emitting elements in the second sub-pixel are symmetrical. The first sub-pixel includes an identification pattern for distinguishing the first sub-pixel from the second sub-pixel.

Abstract: A display device includes a display panel including pixels in one pixel column and a gate driver for sequentially providing scan signals to the pixels. Each of the pixels includes a light emitting element, a first transistor for controlling a current amount of driving current flowing through the light emitting element and a second transistor for transferring a data signal to a gate electrode of the first transistor in response to a corresponding scan signal among the scan signals. A first pixel among the pixels is electrically connected to a first data line, and a second pixel adjacent to the first pixel among the pixels is electrically connected to a second data line different from the first data line. A second scan signal provided to the second pixel partially overlaps with a first scan signal provided to the first pixel.
