## Abstract

An electronic device includes a substrate, a spacer, a first element and a second element. The spacer is disposed on the substrate and has a first portion, a second portion, a first opening, a second opening and a third opening arranged in a first direction. In a cross-section view, the second opening is located between the first opening and the third opening, the first portion is located between the first opening and the second opening, and the second portion is located between the second opening and the third opening. A width of the first portion is less than a width of the second portion in the first direction, and an area of the second opening is different from an area of the first opening. The first element is overlapped with the first opening. The second element is overlapped with the third opening.

## Claims
