Abstract

Claims (14)

1 . A display panel comprising: a first substrate and a second substrate disposed opposite to the first substrate, wherein an electrophoresis layer and electrophoresis ions are disposed on the first substrate, the electrophoresis layer is located between the second substrate and the first substrate, the electrophoresis layer is provided with a plurality of electrophoresis tanks arranged in an array, openings of the plurality of electrophoresis tanks face the second substrate, and the electrophoresis ions are located in the plurality of electrophoresis tanks;

wherein one of the electrophoresis layer and the second substrate is provided with a positioning groove, the other of the electrophoresis layer and the second substrate is provided with a positioning block embedded into the positioning groove, and orthographic projections of the positioning groove and the positioning block on the first substrate are at least partially located between orthographic projections of two adjacent electrophoresis tanks on the first substrate;

wherein:

a surface of the electrophoresis layer facing the second substrate is provided with the positioning groove, there are a plurality of positioning grooves arranged in an array, and each of the plurality of positioning grooves correspondingly surrounds one electrophoresis tank; and

the positioning block is protruded on one side of the second substrate facing the electrophoresis layer, there are a plurality of positioning blocks arranged in an array, and the plurality of positioning blocks are embedded into the plurality of positioning grooves in a one-to-one correspondence and each correspondingly surrounds one electrophoresis tank;

wherein one side of the second substrate facing the first substrate is further provided with a sealant layer, and the sealant layer is a transparent adhesive; and

wherein the sealant layer covers the plurality of positioning blocks and is fitted with inner groove walls of the plurality of positioning grooves.

2 .
