Abstract
According to an embodiment of the present invention, an active matrix substrate () includes a display region (DR) defined by a plurality of pixel regions (P) arranged in a matrix and a peripheral region (FR) located around the display region. The active matrix substrate includes a substrate (), a first TFT (), and a second TFT (). The first TFT is supported by the substrate and disposed in the peripheral region. The second TFT is supported by the substrate and disposed in the display region. The first TFT includes a crystalline silicon semiconductor layer (), which is an active layer. The second TFT includes an oxide semiconductor layer (), which is an active layer. The first TFT and the second TFT each have a top-gate structure.
