Organic electroluminescent device and manufacturing method thereof

摘要

An organic electroluminescent device includes a plurality of main pixels. Each of the main pixels includes red, green, and blue sub-pixels. Each of the sub-pixels includes a first electrode, a second electrode opposite to the first electrode, and an organic light emitting layer between the first and second electrode. The organic light emitting layer of each of the sub-pixels includes a blue light emitting layer and a green light emitting layer. Optical microresonator distances of the red, green, and blue sub-pixels are different from each other.

1. An organic electroluminescent device comprising:
a plurality of main pixels, each of the main pixels comprising a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein each of the red sub-pixel, the green sub-pixel, and the blue sub-pixel comprises:
a first electrode;a second electrode opposite to the first electrode; andan organic light emitting layer between the first electrode and the second electrode, the organic light emitting layer comprising a blue light emitting layer and a green light emitting layer,wherein one of the first electrode or the second electrode comprises a semitransparent material and an other one of the first electrode or the second electrode comprises a light reflection material, and wherein an optical microresonator distance is defined between the first electrode and the second electrode, the optical microresonator distance of one of the red sub-pixel, the green sub-pixel, or the blue sub-pixel is different from the optical microresonator distance of other ones of the red sub-pixel, the green sub-pixel, or the blue sub-pixel.
