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.
