DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240206298 titled 'DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

The present disclosure pertains to a display device comprising a substrate, a light-emitting element with an emission layer on the substrate, and a light controller on the light-emitting element. The light controller includes multiple light blocking parts extending in one direction and spaced along another direction, with a transparent organic layer between them. Each light blocking part consists of at least one light absorption layer and one compensation layer stacked alternately along the substrate's thickness direction, where the absorption layer has compressive stress and the compensation layer has tensile stress.
