Electrowetting display device and manufacturing method thereof

摘要

An electrowetting display device includes: a lower substrate, a pixel electrode disposed on the lower substrate, a lower water-repellent layer disposed on the pixel electrode, a plurality of partitions disposed on the lower water-repellent layer and an oil layer disposed on the lower water-repellent layer between the partitions, and wherein the partitions include a side wall having a reverse taper structure.

主权项

1. An electrowetting display device comprising:
a lower substrate; a pixel electrode disposed on the lower substrate; a lower water-repellent layer comprising a first material disposed on the pixel electrode; partitions disposed on the lower water-repellent layer, wherein the partitions have a reverse taper cross-section so that a thickness of the partitions decreases in a direction from a top of the partitions toward the lower water-repellent layer; an upper water-repellent layer comprising a second material different from the first material of the lower water-repellent layer, the upper water-repellent layer disposed (i) on the lower water-repellent layer and (ii) between the partitions; and an oil layer disposed on the upper water-repellent layer between the partitions.
