Abstract
An organic light-emitting diode (OLED) display includes a substrate and a plurality of sub-pixels formed on the substrate, wherein the substrate includes a display region having formed therein sub-pixels to which colored organic materials are applied, and a non-display region formed at edges of the display region. The non-display region includes an outgassing portion and a cathode contacting portion, and protrusions and recessions having different numbers and unit opening areas are formed in at least one of the outgassing portion and the cathode contacting region. Thus, organic raw materials applied during manufacturing process may be prevented from remaining. Therefore, an increase in contact resistance due to organic raw materials remaining in a cathode contact region may be reduced.
