Claim:
1. An organic display device, comprising at least one infrared display pixel, wherein the infrared display pixel comprises a flexible transparent substrate which is deposited with a first electrode layer, an infrared organic light emitting layer and a second electrode layer thereon, and the infrared organic light emitting layer is filled with an infrared light emitting material; wherein the infrared display pixel further comprises a first protective layer and a second protective layer, the first protective layer is formed between the transparent substrate and the first electrode layer, and the second protective layer having a closed bent shape is configured to form a protective space between the first protective layer and the second protective layer so that the infrared organic light emitting layer has at least one sidewall contacting with the second protective layer; wherein the first protective layer comprises at least one polymer layer and at least one cutoff layer, and the polymer layer and the cutoff layer are alternately superimposed with each other; wherein the transparent substrate is formed with scan lines, data lines, a power lines and switch array elements, the infrared display pixel connects to the scan line, the date line and the power line through the switch array element, and the infrared display pixel is switched on or off according to signals from the scan line, the date line and the power line, wherein the infrared light emitting material is a trivalent rare-earth ion complex having an infrared light emitting wavelength ranged from 0.76 micrometers to 400 micrometers.
