    Abstract: The present disclosure provides a driving substrate including: a flexible substrate base, a plurality of thin film transistors on the flexible substrate base and a first conductive pattern layer on a side of the thin film transistors distal to the flexible substrate base. The first conductive pattern layer includes: a plurality of first connection terminals in the display region and a plurality of signal supply lines in the bendable region. A first number of first connection terminals are electrically coupled to first electrodes of the plurality of thin film transistors. The plurality of signal supply lines are coupled to a second number of first connection terminals other than the first number of first connection terminals. At least one inorganic insulating layer including a hollowed-out pattern in the bendable region is between the first conductive pattern layer and the flexible substrate base.

    Abstract: A display device is disclosed. The display device includes a display area and a wiring area. The display area is disposed with a first thin film transistor which is an oxide thin film transistor and a second thin film transistor which is a low temperature poly-silicon thin film transistor. A distance between a first active layer of the first thin film transistor and a substrate is different from a distance between a second active layer of the second thin film transistor and the substrate. The first thin film transistor includes first vias that receive a first source/drain. The second thin film transistor includes second vias that receives a second source/drain. The wiring area is provided with a groove. The groove includes a first sub-groove and a second sub-groove that are stacked, and depths of the second vias are substantially equal to a depth of the second sub-groove.
