The present disclosure provides a display apparatus, a display panel, and a method of manufacturing a display panel. The display panel includes a base substrate, a conductive layer, an organic insulating structure, a first organic convex ring, and a cathode material layer. A first isolation trench for exposing the conductive layer is provided between the organic insulating structure and the first organic convex ring, and a ratio of a width of the first isolation trench to a maximum allowable fluctuation for a distance between an edge position of the cathode material layer and an edge of the organic insulating structure ranges from 0.025 to 0.218. According to embodiments of the present disclosure, when a distance between an edge of a cathode and an outer edge of a frame area is fixed, the maximum allowable fluctuation for the distance between the edge position of the cathode material layer and the edge of the organic insulating structure may be increased by reducing the width of the first isolation trench. As a result, the cathode material layer may not fall into the first isolation trench in the evaporation process, so as to avoid short circuit due to overlap of the cathode with the conductive layer, thereby improving the yield of the display panel.
