Abstract
A display may include one or more display pixels in an array of pixels. A display pixel may include a storage capacitor chat stores a pixel data signal. The storage capacitor may be formed from a pixel electrode structure, a capacitor electrode structure, and a common electrode structure that is interposed between the pixel electrode structure and capacitor electrode structures. Each electrode structure may be formed from transparent conductive materials deposited on respective display layers. The pixel electrode structure and capacitor electrode structure may be electrically coupled by a conductive via structure that extends through the display layers without contacting the common electrode structure. The conductive via structure may contact underlying transistor structures such as a source-drain structure.
