Abstract
A display device includes a display element, a transistor configured to drive the display element, the transistor including a channel region, and a retention capacitor. An oxide semiconductor film is provided in areas across the transistor and the retention capacitor, the oxide semiconductor film including a first region formed in the channel region of the transistor, and a second region having a lower resistance than that of the first region. The second region is formed in the areas of the transistor and retention capacitor other than in the channel region.
