Abstract

An electronic device is provided. The electronic device includes a working region and a non-working region adjacent to the working region. The electronic device includes a first substrate, a first photo spacer, a second photo spacer, and a plurality of third photo spacers. The first photo spacer is disposed on the first substrate in the working region and has a first thickness. The second photo spacer is disposed on the first substrate in the non-working region and has a second thickness. The plurality of third photo spacers are disposed on the first substrate. The first photo spacer is disposed between two of the plurality of third photo spacers. At least one of the plurality of third photo spacers has a third thickness. The first thickness is different from the second thickness, and the third thickness is less than the first thickness.
