Liquid crystal display and method of manufacturing the same

Abstract

A liquid crystal display includes: a substrate; a thin film transistor; a pixel electrode; a roof layer; a liquid crystal layer; and a plurality of partitions. The thin film transistor is disposed on the substrate. The pixel electrode is connected to the thin film transistor. The roof layer is disposed to face the pixel electrode. The liquid crystal layer is formed by a plurality of microcavities between the pixel electrode and the roof layer, wherein the microcavities include a liquid crystal material. The partitions are between the microcavities adjacent to each other, wherein the partitions may include an organic material and are arranged side by side to one another.
