Abstract:
1. An organic light emitting diode (OLED) display comprising: first electrodes respectively connected to thin film transistors formed on a substrate; bank patterns formed on boundary regions between the first electrodes to partition opening regions of pixels; a first layer formed to cover all of the bank patterns and the first electrodes exposed between the bank patterns, wherein the first layer is a hole injection layer and/or a hole transport layer; organic emitting patterns formed on the first layer in the opening regions of the pixels defined by the bank patterns; a second layer formed to cover the organic emitting patterns and the first layer exposed between the organic emitting patterns; and second electrodes formed on the second layer to cross over the first electrodes, wherein the organic emitting patterns comprise a mixture of at least two organic materials, and wherein a difference of sublimation temperatures between the at least two organic materials is set to be less than 50° C.
