The present disclosure relates to an ultra high density display having high aperture ratio. The present disclosure suggests a display comprising: a upper horizontal current line, a horizontal sensing line, a scan line and a lower horizontal current line running in horizontal direction and sequentially disposed in vertical direction on a substrate in this order from the upper side to the lower side; an emission area defined between the horizontal sensing line and the upper horizontal current line; a non-emission area defined between the horizontal sensing line and the lower horizontal current line; a switching thin film transistor and a sensing thin film transistor disposed between the horizontal sensing line and the scan line; a driving thin film transistor disposed between the scan line and the lower horizontal current line; an anode electrode expanded from the emission area to the non-emission area, and connected to the driving thin film transistor; and an anode bottle neck part disposed between the horizontal sensing line and the scan line for disconnecting the anode electrode from the driving thin film transistor selectively.
