DISPLAY DEVICE

A display device includes a plurality of sub-pixels arranged in a first direction and in a second direction; a plurality of data lines extending in the second direction; first data connection lines in the display area, and extending in the second direction, a first data connection line of the first data connection lines being spaced in the first direction from a data line of the plurality of data lines in a sub-pixel of the plurality of sub-pixels; and second data connection lines in the display area, extending in the first direction and coupled to at least one of the first data connection lines. The sub-pixel includes a first connection electrode coupled to a first electrode of a driving transistor of the sub-pixel, and the first connection electrode does not overlap the first data connection line and is between the first data connection line and the data line.
