Abstract
A liquid crystal display includes a substrate; a first electrode on the substrate; a second electrode on the first electrode and separated from the first electrode; a cavity defined between the first electrode and the second electrode; a first protection layer on the second electrode; a cover layer on the first protection layer; and a liquid crystal layer including liquid crystal molecules in the cavity. The second electrode includes metal oxide and zinc oxide.
Claims21
A liquid crystal display comprising:
- a substrate;
- a first electrode on the substrate;
- a second electrode comprising metal oxide and zinc oxide, on the first electrode and spaced apart from the first electrode;
- a cavity provided in plural defined between the first electrode and the second electrode;
- an inlet portion which is defined between adjacent cavities and exposes inner areas thereof;
- a first protection layer which is directly on the second electrode and disposes the second electrode between the substrate and the first protection layer;
- a cover layer which is on the first protection layer and disposes the first protection layer between the second electrode and the cover layer;
- and
- a liquid crystal layer comprising liquid crystal molecules, in the cavity,
- wherein with the first protection layer directly on the second electrode comprising the metal oxide and the zinc oxide, and each of the second electrode, the first protection layer and the cover layer terminate at the inlet portion to expose the inlet portion.
A method for fabricating a liquid crystal display, comprising:
- forming a first electrode on a substrate;
- forming a sacrificial layer on the first electrode;
