## Abstract

An electronic structure includes a substrate, a plurality of electronic units disposed on the substrate, and a circuit structure electrically connected with at least one of the plurality of electronic units. The substrate has a first flat part and a curved part connected with the first flat part. Two adjacent ones of the plurality of electronic units on the first flat part have a first pitch in a first direction parallel to a surface of the first flat part Another two adjacent ones of the plurality of electronic units on the curved part have a second pitch different from the first pitch in a second direction parallel to a surface of the curved part. In a normal direction of the first flat part, at least a portion of the circuit structure overlaps a region between another two of the plurality of electronic units on the first flat part.

## Claims
