A display apparatus includes: a scan line extending in a first direction; a first data line and a second data line extending in a second direction crossing the first direction; a fixed voltage line extending in the second direction between the first and second data lines and configured to receive a fixed voltage; an auxiliary line between the fixed voltage line and one of the first and second data lines, wherein the fixed voltage is applied to the auxiliary line; a transistor circuit comprising a second transistor coupled to the scan line and the first data line and a first transistor coupled to the second transistor and the fixed voltage line; and a light emitting device coupled to the transistor circuit, wherein at least a portion of the transistor circuit is between the fixed voltage line and the auxiliary line.
