1. An encapsulated display panel, comprising:
a display substrate;
a counter substrate facing the display substrate; and
a sealant filled in a space between the display substrate and a counter substrate;
wherein the display substrate in a peripheral area has a plurality of protruding parts and a plurality of recessing parts, resulting in an uneven surface topography;
the counter substrate in at least a portion of the peripheral area has a counter surface topography substantially complementary to the surface topography of the display substrate, the counter substrate in the peripheral area has a plurality of counter protruding parts;
the counter substrate in the peripheral area has a plurality of corner protrusions abutting a plurality of corners of the sealant frame, respectively;
a respective one of the plurality of corner protrusions is in direct contact with the sealant frame; and
the respective one of the plurality of corner protrusions protrudes into a recess having the sealant and the sealant frame as side walls.
