Abstract

A display device includes a substrate (111) including a first area (AAl) including first subpixels (SP1) and a transmissive part (TA), and a second area (AA") including second subpixels (SP2). A first transistor (T1) in the first area (A1) includes an oxide semiconductor active layer (ACT1), a gate electrode (G1), and first and second source-drain electrodes (SD11, SD12). A second transistor (T2) disposed in the first area (AA1) includes an oxide semiconductor active layer (ACT2) including first and second active layers (A21, A22), a gate electrode (G2), and first and second source-drain electrodes (SD21, SD22). A light-emitting element (135) is disposed in the first area (AA1). A third transistor (T3) is connected between the second transistor (T2) and the light-emitting element (135) and includes an oxide semiconductor active layer (ACT3) including first and second active layers (A31, A32), a gate electrode (G3), and first and second source-drain electrodes (SD31, SD32). The second active layer (A32) of the third transistor (T3) has a higher carrier mobility than the first active layer (A31) of the third transistor (T3).
