Abstract
The present disclosure relates to an organic light emitting display panel and a display apparatus. The organic light emitting display panel includes: a first substrate provided with a plurality of pixels each comprising an organic light emitting diode; a second substrate having at least one auxiliary electrode electrically connected to a cathode of the organic light emitting diode, each auxiliary electrodes being located on a side of the second substrate facing the first substrate and corresponding to a gap between adjacent pixels on the first substrate; and an antireflection layer formed on the auxiliary electrode for absorbing light rays directed to the auxiliary electrode. In the present disclosure, by the auxiliary electrode formed on the second substrate and electrically connected to the cathode on the first substrate, the voltage drop of the cathode may be significantly reduced, and the uniformity of the display brightness is improved. Meanwhile, by the antireflection layer formed on the auxiliary electrode, light leakage phenomenon due to reflection of a metal auxiliary electrode may be prevented, thereby improving contrast ratio of the display.
