Abstract

An electronic device has a viewing side and includes a first substrate, a second substrate, two adjacent first switching components, a third substrate and two adjacent second switching components. The second substrate is overlapped with the first substrate along a first direction. The first switching components are disposed between the first substrate and the second substrate, wherein the first switching components are separated by a first distance along a second direction different from the first direction. The third substrate is overlapped with the second substrate along the first direction. The second switching components are disposed between the second substrate and the third substrate, wherein the second switching components are closer to the viewing side than the first switching components, the second switching components are separated by a second distance along the second direction, and the second distance is greater than the first distance.
