The invention provides a display device, a transflective type thin film transistor array substrate and a manufacture method thereof. The manufacture method comprises the steps of providing a substrate; forming a gate line, a data line which is broken at a position passing a gate line area, a gate electrode, a reflecting electrode and a public electrode line on the substrate, wherein the gate line is perpendicular to the data line, the gate line is connected with the gate electrode, an area which the reflecting electrode locates in is a reflecting area, and an area between the reflecting electrode and the public electrode line is a transmission area; forming a patterned gate insulating layer on the gate line, the data line, the gate electrode, the reflecting electrode and the public electrode line, and forming an active layer on the gate insulating layer; forming a pixel electrode, a source electrode, a drain electrode, a broken data line connecting line and a channel on the patterned gate insulating layer and the active layer; forming a passivation layer and a public electrode through hole on the pixel electrode the source electrode and the drain electrode; and forming a public electrode on the passivation layer. The display device, the transflective type thin film transistor array substrate and the manufacture method thereof can resolve the problem of poor display effect under strong light.
