DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18142831 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

Simplified Explanation

The abstract describes a display device with specific layers and components.

  • The device includes a substrate, which serves as a base.
  • A lower metal layer is placed on the substrate.
  • A light emitting element is positioned on the lower metal layer.
  • The light emitting element consists of a lower electrode, a light emitting layer, and an upper electrode.
  • A pixel defining layer is placed on the lower metal layer, exposing part of the lower electrode.
  • A residual sacrificial layer is added on top of the pixel defining layer.
  • The residual sacrificial layer separates portions of the upper electrode, disconnecting them from each other.


Original Abstract Submitted

A display device includes a substrate, a lower metal layer disposed on the substrate, a light emitting element disposed on the lower metal layer, where the light emitting element includes a lower electrode, a light emitting layer, and an upper electrode sequentially disposed, a pixel defining layer disposed on the lower metal layer, where the pixel definition layer exposes at least a portion of the lower electrode, and a residual sacrificial layer disposed on the pixel defining layer, where portions of the upper electrode are disconnected from each other with the residual sacrificial layer therebetween.
