## Abstract

An active device array structure including a substrate including a first region and a second region, and first signal lines, second signal lines, third signal lines, and active devices disposed on the substrate is provided. A bending degree of the first region is greater than that of the second region. The first signal lines and the second signal lines cross through the first region and the second region. Each first signal line includes a first multi-segments structure located in the first region. Each first multi-segments structure includes first segments connected in parallel. An extending direction of the third signal lines is intersected with the first signal lines and the second signal lines. Each third signal line is electrically connected to one first signal line. The active devices are electrically connected to the second and the third signal lines, or the first and the third signal lines.
