PROCESS FOR PREPARING A DISPLAY PANEL
First Claim
1. A process for preparing a display panel comprising the steps of:
- a) forming microcups on a conductor layer which is on a plastic substrate;
b) filling the microcups with an electrophoretic fluid;
c) overcoating a top-sealing composition on the electrophoretic fluid; and
d) hardening the sealing composition while on top of the electrophoretic fluid.

Abstract
This application is directed to processes for preparing electrophoretic displays and semi-finished display panels comprising display cells prepared from the microcup and top-sealing technologies. The semi-finished display panel comprises an array of display cells sandwiched between two temporary substrate layers, between a temporary substrate layer and a conductor layer or between a temporary substrate layer and a permanent substrate layer, wherein said display cells are filled with an electrophoretic fluid and top-sealed with a polymeric sealing layer formed from a top-sealing composition which is being hardened while on top of the electrophoretic fluid.
