Abstract
An OLED panel includes a plurality of light-emitting elements, that each light-emitting element includes a fence structure on a substrate and in an opening of a pixel definition layer. A trench is formed between the fence structure and the pixel definition layer. Charge transport layer is disconnected at the trench by a shadowing effect of the fence structure during thermal evaporation of the charge transport layer. Therefore, lateral current leakage between two adjacent light-emitting elements is minimized.
