摘要： In an organic light emitting diode (OLED) display device and a method for fabricating the same, OLED pixels are patterned through a photolithography process, so a large area patterning can be performed and a fine pitch can be obtained, and an organic compound layer can be protected by forming a buffer layer of a metal oxide on an upper portion of the organic compound layer or patterning the organic compound layer by using a cathode as a mask, improving device efficiency. In addition, among red, green, and blue pixels, two pixels are patterned through a lift-off process and the other remaining one is deposited to be formed without patterning, the process can be simplified and efficiency can be increased.
摘要翻译： 在有机发光二极管（OLED）显示装置及其制造方法中，OLED像素通过光刻工艺被图案化，因此可以进行大面积的图案化，并且可以获得精细的间距，并且有机化合物层可以 通过在有机化合物层的上部形成金属氧化物的缓冲层或通过使用阴极作为掩模来对有机化合物层进行图案化来保护，从而提高器件效率。 此外，在红色，绿色和蓝色像素中，通过剥离工艺对两个像素进行图案化，其余剩余的一个被沉积以形成，而无需图案化，可以简化工艺并提高效率。
