Abstract

A liquid crystal display device including a substrate, a thin film transistor provided at an area adjacent to an intersection of a gate line and a data line on the substrate, a protective layer provided on the substrate to cover the thin film transistor, a pixel electrode provided on the protective layer and connected through the protective layer to the thin film transistor, a first hole in a surface of the pixel electrode and positioned above an adjacent gate line and a spacer positioned within the first hole. A method of fabricating a liquid crystal display device includes the steps of forming a thin film transistor at an area adjacent an intersection between a gate line and a data line on a substrate, forming a protective layer covering the thin film transistor, forming a pixel electrode provided on the protective layer and passing through the protective layer to be electrically connected to the thin film transistor, defining a hole in a surface of the pixel electrode by patterning the pixel electrode on the protective layer above an adjacent gate line and depositing a spacer into the first hole using an ink-jet device.

Claims (14)

1. A liquid crystal display device, comprising:

a substrate;

a thin film transistor provided at an area adjacent to an intersection of a gate line and a data line on the substrate;

a protective layer provided on the substrate to cover the thin film transistor;

a pixel electrode provided on the protective layer and connected to the thin film transistor through a contact hole of the protective layer, the pixel electrode defining a first hole that is positioned above an adjacent gate line; and

a spacer positioned within the first hole such that a lower part of the spacer is entirely encircled by the pixel electrode, wherein a bottom surface of the spacer directly contacts the protective layer.

2. The liquid crystal display device of claim 1 , wherein the first hole overlaps the adjacent gate line.

3. A method of fabricating a liquid crystal display device, comprising the steps of:

forming a thin film transistor at an area adjacent an intersection between a gate line and a data line on a substrate;

forming a protective layer covering the thin film transistor;

forming a pixel electrode provided on the protective layer and passing through a contact hole of the protective layer to be electrically connected to the thin film transistor;

forming a hole in a surface of the pixel electrode by patterning the pixel electrode on the protective layer above an adjacent gate line; and

depositing a spacer onto the protective layer exposed by the first hole using an ink-jet device such that a lower part of the spacer is entirely encircled by the pixel electrode, wherein a bottom surface of the spacer directly contacts the protective layer.

4. The method of claim 3 , wherein the first hole within the pixel electrode overlaps the adjacent gate line.
