Patent ID: 8035300

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