Abstract

The present invention provides a top-emission type micro cavity OLED display device, comprising: an array substrate; a reflection metal layer arranged on the array substrate; an anode modulation layer arranged on the reflection metal layer and made of a translucent conductive material; an organic light-emitting layer arranged on the anode modulation layer and not patterned; and a cathode layer arranged on the organic light-emitting layer. The top-emission type micro cavity OLED display device comprises a plurality of sub-pixels, and the anode modulation layer is divided into a plurality of anode modulation electrodes corresponding to the plurality of sub-pixels; the plurality of sub-pixels is at least classified into a first type sub-pixel, a second type sub-pixel and a third type sub-pixel; the first to third type sub-pixels display different colors, and the anode modulation electrodes corresponding to the first to third type sub-pixels have different thicknesses.
