Classification: CPC H  G | IPC G  H

Claim 4:
5. A display device comprising:
a first substrate;
a second substrate facing the first substrate;
a liquid crystal layer between the first substrate and the second substrate;
a light-shielding film between the liquid crystal layer and the second substrate,
wherein a pixel over the first substrate comprising:
a semiconductor film over the first substrate;
a gate wiring overlapping with the semiconductor film with a gate insulating film interposed therebetween, the gate wiring extending along a first direction;
a first wiring extending along the first direction;
a second wiring over and electrically connected to the semiconductor film, the second wiring comprising metal;
an organic resin layer over the second wiring;
a transparent conductive film over the organic resin layer; and
a metal film over and in direct contact with a top surface of the transparent conductive film;

wherein the metal film comprises an opening,
wherein the transparent conductive film comprises a first region, a second region, and a third region,
wherein the first region of the transparent conductive film is in direct contact with the metal film,
wherein neither the second region nor the third region is in direct contact with the metal film,
wherein the first region is provided so as to surround the second region when seen from a direction perpendicular to a top surface of the first substrate,
wherein the first region is not a display region,
wherein the third region is outside the second region when seen from the direction perpendicular to the top surface of the first substrate, and
wherein at least part of the first region is between the second region and the third region when seen from the direction perpendicular to the top surface of the first substrate,
wherein the light-shielding film overlaps with the first region when seen from the direction perpendicular to the top surface of the first substrate,
wherein the light-shielding film overlaps with a region between a first part of the first region which extends along the first direction and the gate wiring when seen from the direction perpendicular to the top surface of the first substrate,
wherein a second part of the first region which extends along the first direction overlaps with the first wiring, and
wherein the second region of the transparent conductive film is between the first part of the first region and the second part of the first region.
