Abstract
The present application provides an OLED display panel and an OLED display panel manufacturing method forming at least one crack-proof recess surrounding a display region on an array substrate. When the OLED display panel performs a laser cutting process to a cutting line region on the array substrate, cracks generated from the cutting line region is interrupted by the crack-proof recess and therefore cannot extend into a deep inside of a non-display region, and cannot further extend into the display region, which prevents a technical issue of a lowered yield rate due to extension of cracks into the display region.
