Each light-transmitting region unit includes first and second sets of light-transmitting regions that are arranged along a first direction. The first set of light-transmitting regions includes a first light-transmitting region and a second light-transmitting region arranged along a second direction, and the second set of light-transmitting region includes a third light-transmitting region and a fourth light-transmitting region arranged along the second direction. The first direction intersects with the second direction. Each light-transmitting region has a length direction. An angle formed between the length direction and the first direction is within a range of 10° to 40°. In each light-transmitting region unit, the length direction of each light-transmitting region points to an area surrounded by the first to fourth light-transmitting regions.
