1. A process for producing an electro-optic display having a color filter array, which process comprises:
- providing an electro-optic display comprising a direct thermal imaging layer and a backplane having a two-dimensional array of pixel electrodes wherein the direct thermal imaging layer comprises a plurality of layers of material, each layer capable of switching to a color; and
exposing the direct thermal imaging layer to temperatures sufficient to form a plurality of differently colored areas in the direct thermal imaging layer, the plurality of differently colored areas being aligned with the two-dimensional array of pixel electrodes.

Abstract
An electro-optic display having a color filter array is produced by attaching together a direct thermal imaging layer (112) and a backplane (102) having a two-dimensional array of pixel electrodes. The direct thermal imaging layer (112) is then exposed to temperatures sufficient to form a plurality of differently colored areas in the direct thermal imaging layer, the plurality of differently colored areas being aligned with the two-dimensional array of pixel electrodes.
