A display device is manufactured with five photolithography steps: a step of forming a gate electrode, a step of forming a protective layer for reducing damage due to an etching step or the like, a step of forming a source electrode and a drain electrode, a step of forming a contact hole, and a step of forming a pixel electrode. The display device includes a groove portion which is formed in the step of forming the contact hole and separates the semiconductor layer. |
