Abstract
A display device includes a semiconductor layer on an opposite side to a light-blocking layer, the semiconductor layer including an active layer overlapping the light-blocking layer, a first gate insulator on an opposite side to a buffer film with the active layer therebetween, and a first gate electrode on an opposite side to the active layer with the first gate insulator therebetween, a side surface of the first gate insulator includes a first inclined portion contacting a first surface of the semiconductor layer, and a second inclined portion contacting the first inclined portion and the first gate electrode, and a first angle between the first surface of the semiconductor layer and the first inclined portion is less than a second angle between the first surface of the semiconductor layer and the second inclined portion.
