摘要： A display apparatus (1000) according to an embodiment can include a first electrode (400), a plurality of organic layers, a second electrode (700), and a metal layer (600) disposed on a particular organic layer (POL) among the plurality of organic layers. The metal layer (600) is configured to protect the particular organic layer (POL) from being damaged when it is exposed to a non-vacuum environment at least once during processes of stacking the organic layers on the first electrode and the second electrode (700) on the organic layers in a vacuum environment, thereby suppressing a rise in the driving voltage of the display apparatus. Accordingly, the problems that the driving voltage of the display apparatus increases and the lifespan is shortened can be addressed.

摘要： Provided is a display device (100, 300, 400). The display device (100, 300, 400) includes an organic light emitting diode (140) which is disposed in a first pixel (PX1) configured to emit a first color light, a second pixel (PX2) configured to emit a second color light, and a third pixel (PX3) configured to emit a third color light and emits the third color light, a first color-conversion layer (151) disposed on the organic light emitting diode (140) in the first pixel (PX1), and a second color-conversion layer (152) disposed on the organic light emitting diode (140) in the second pixel (PX2). Accordingly, it is possible to reduce a difference in intensity between light generated by the organic light emitting diode (140) and light generated by each pixel and thus increase the light efficiency of the display device (100, 300, 400).
