Abstract
The present invention discloses an OLED device with an optical resonance layer and fabricating method thereof, and a display device. The OLED device comprises: a white light OLED and a color filter film, so as to form an R sub-pixel, a G sub-pixel, a B sub-pixel and a W sub-pixel, wherein an optical resonance layer is disposed at least in a region corresponding to the G sub-pixel between the white light OLED and the color filter film. By providing the optical resonance layer, the OLED device with an optical resonance layer of the present invention can filter monochromatic lights with good chromaticity and high efficiency, even by using a color filter film with a low color gamut, and specially, the problem of the low display quality in white light OLED+CF technology at present is solved. In addition, the OLED device of the present invention also greatly reduces the power consumption. Moreover, there is no need to use a fine metal mask (FMM), thereby reducing the processing cost.
