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.
