In the unfolded state, the first inflexible portion 12 and the flexible portion 14 can form a substantially planar structure, that is, the first inflexible portion 12 and the flexible portion 14 can be substantially coplanar and folded. In the state, the flexible portion 14 can be bent in the second direction D2 according to the first direction D1, wherein the first direction D1 and the second direction D2 are substantially orthogonal to each other, and the folding angle of the flexible portion 14 is Or the curvature can be adjusted depending on the application. As shown in FIG. 3, the first pixel array 20 is disposed on the first inflexible portion 12 of the substrate 10, wherein the first pixel array 20 includes a plurality of first pixels 20P, the first pixel The 20P may include a plurality of sub-pixels arranged in an array and used to display different colors such as a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In addition, the second pixel array 30 is disposed on the flexible portion 14 of the substrate 10, wherein the second pixel array 30 includes a plurality of second sub-pixels 30P, and the second pixel 30P may include a plurality of pixels. The arrays are arranged to display sub-pixels of different colors such as red sub-pixels, green sub-pixels and blue sub-pixels.
