Title: (EN) Display device
Abstract: front page image
(EN)

Embodiments of the invention disclose a display device, comprising a substrate, a plurality of pixels on the substrate and a backlight module located at a side of the substrate away from the pixels. Each pixel has a microcavity structure, in which the light emitted from the backlight module oscillates many times and exits as visible light of at least three colors, thereby enabling the display device to realize color display. Compared to the existing liquid crystal display device, this display device will not be limited by the manufacturing process when it is applied in the flexible display field. Compared to the existing organic electroluminescent display device, this display device will not have the problems of low yield, high cost and short life time, etc.
