Abstract: A display device includes: a substrate in which a transmission area, a display area, a non-display area and the display area, and a peripheral area are defined; pixels arranged on the display area; initialization gate lines and compensation gate lines extending along pixel rows; gate driving circuits disposed on the peripheral area; and gate connection lines disposed on the non-display area. A k-th gate driving circuit among the gate driving circuits simultaneously drives m-th and (m+1)-th initialization gate lines and n-th and (n+1)-th compensation gate lines. First portions of the n-th and (n+1)-th compensation gate lines and second portions of the n-th and (n+1)-th compensation gate lines, which are physically apart from each other by the transmission area, are electrically connected to each other through a first gate connection line among gate connection lines.
