Abstract: An array substrate, a display panel, and a display device are provided. The array substrate includes a base; a buffer layer and a thin film transistor. The buffer layer is provided on the base and includes a first buffer layer and a second buffer layer. The first buffer layer is disposed between the second buffer layer and the base. A refractive index of the first buffer layer is greater than a refractive index of the base and a refractive index of the second buffer layer. A ratio of the refractive index of the first buffer layer to the refractive index of the base is less than or equal to 1.25. The thin film transistor is provided on a side of the buffer layer away from the base.

Abstract: A semiconductor device, a display panel, and a chip are provided in embodiments of the present application. The semiconductor device of the embodiments of the present application stacks a first conductor portion, a channel portion, and a second conductor portion to form a vertical active structure layer to realize a narrow channel. A growth direction of crystal grains arranged in the channel potion is consistent with a moving direction of carriers to provide a single crystal-like channel.
