Abstract
Disclosed is a method of making a flat panel display device including a first substrate, an array of pixels, a second substrate opposing the first substrate, and a frit formed between the first substrate and the second substrate to encapsulate the array. A buffer layer is formed on the first substrate, an insulating film is formed on the buffer layer, and a portion of the insulating film is etched. A metal conductive line is formed on the etched portion and on the non-etched portion of the insulating film. A protective film is formed on the insulating film and the conductive line.
Claims21
A method of making a display device, the method comprising:
- providing a first substrate, an insulating layer formed over the first substrate and a structure interposed between the first substrate and the insulating layer;
- selectively etching a portion of the insulating layer so as to expose a portion of the structure;
- forming a conductive line on the exposed portion of the structure and the non-etched portion of the insulating layer, wherein the conductive line generally extends in a first direction and comprising a first portion which is formed on the exposed portion of the structure, wherein the conductive line has a width in the first portion thereof, the width being measured in a second direction perpendicular to the first direction, wherein the exposed portion of the structure has a width measured in the second direction, and wherein the width of the exposed portion is greater than the width of the conductive line in the first portion;
- forming a protective layer over the conductive line and a non-etched portion of the insulation layer;
- arranging a second substrate relative to the first substrate such that the protective layer is interposed between the first and second substrates;
- interposing a frit between the protective layer and second substrate;
- and
- wherein the frit overlaps with the first portion of the conductive line when viewed in a third direction from the first substrate, and wherein the third direction is perpendicular to the first and second directions.

A display device comprising:
- a first substrate;
- a second substrate opposing the first substrate;
- a frit seal interposed between the first substrate and the second substrate;
- a conductive line generally extending in a first direction and comprising a first portion which is interposed between the first substrate and the frit seal, wherein the conductive line has an width in the first portion thereof measured in a second direction, which is perpendicular to the first direction, wherein the frit seal overlaps with the first portion when viewed in a third direction from the first substrate, the third direction being perpendicular to the first and second directions;
- and
- a protective layer comprising a first portion and a second portion, wherein the first portion of the protective layer is interposed between the frit seal and the first portion of the conductive line, wherein the second portion of the protective layer is interposed between the frit seal and the first substrate while not interposed between the frit seal and the first portion of the conductive line, wherein the protective layer comprises a first surface in the first portion thereof, the first surface facing the second substrate, wherein the protective layer comprises a second surface in the second portion thereof, the second surface facing the second substrate, wherein the protective layer has a first thickness in the first portions thereof, the first thickness being measured in the third direction, and wherein a distance between the first surface and the second surface in the third direction is equal to or smaller than about the first thickness.
