ARRAY SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME, DISPLAY DEVICE

摘要

An array substrate, comprising a display region and a GOA region. In the GOA region, a gate metal electrode, a gate insulating layer, an active layer, a transition layer, and a source-drain metal electrode are formed in sequence from bottom to top, and a via hole is provided penetrating the transition layer, the active layer and the gate insulating layer, the source-drain metal electrode is electrically connected to the gate metal electrode through the via hole; and at an edge of the via hole, there is formed an angle opening upward at edges of the transition layer and the active layer. There are further disclosed a manufacturing method of the array substrate and a display device provided with the array substrate.
