Display device

A display device, comprising:

• a gate electrode;
• an oxide semiconductor layer overlapping the gate electrode;
• a first insulating layer containing an organic insulating material over the oxide semiconductor layer;
• a pixel electrode over the first insulating layer;
• and
• a first connection electrode in contact with the first insulating layer, and connecting the oxide semiconductor layer and the pixel electrode,
• wherein the oxide semiconductor layer is separated into at least two regions between the gate electrode and the first connection electrode,
• wherein the at least two regions are electrically connected to each other through a second connection electrode,
• wherein the first connection electrode contains a transparent conductive oxide, and
• wherein the second connection electrode contains a metal material.
