AI Technical Summary
Technical Problem
In display devices, the light from the light-emitting device is partially blocked by the driving circuit, resulting in a reduction in the effective light-emitting area and affecting image quality.
Method used
A driving circuit and a light-emitting device are set on the device substrate. The driving circuit and the light-emitting area are separated by transparent electrodes and insulating layers to form a main light-emitting area and a sub-light-emitting area. The transmission and emission of light are optimized by stacking storage capacitors and thin-film transistors.
Benefits of technology
It improves the image quality of display devices, increases the effective light-emitting area, simplifies the process, and improves luminous efficiency.

Abstract
A display device includes: a driving circuit comprising a storage capacitor and at least one thin-film transistor; and a light-emitting device comprising a region disposed outside the driving circuit and a region overlapping the storage capacitor, wherein each capacitor electrode of the storage capacitor is a transparent electrode having relatively high transmittance, thereby enabling improved image quality realized on the outer surface of the device substrate supporting the driving circuit and the light-emitting device for each pixel region.
