Claim 0:
1. An organic light emitting diode display device comprising a display area, wherein a first thin film transistor and a second thin film transistor are arranged in the display area, the first thin film transistor comprises a first gate and a first active layer, the second thin film transistor comprises a second gate and a second active layer, a material of the first active layer is different from a material of the second active layer, and wherein the organic light emitting diode display device comprises:
a substrate;
a first insulating layer on the substrate;
a first connection line,
a wiring area provided with a groove; and
a wiring in the groove,
wherein the second active layer is on a side of the first insulating layer away from the substrate;
wherein a second insulating layer is on a side of the second active layer away from the substrate;
wherein the second gate is on a side of the second insulating layer away from the substrate;
wherein a third insulating layer is on a side of the second gate away from the substrate;
wherein the first active layer is on a side of the third insulating layer away from the substrate;
wherein a fourth insulating layer is on a side of the first active layer away from the substrate;
wherein the first gate is on a side of the fourth insulating layer away from the substrate,
wherein the first thin film transistor further comprises a first source and drain, the second thin film transistor further comprises a second source and drain, and the first source and drain are in a same layer as the second source and drain, and
wherein one of the first source and drain is electrically connected with one of the second source and drain through the first connection line, and the first connection line and the second source and drain have a same material and are formed by a same first process.
