Abstract:
1. A semiconductor device comprising: a first substrate over which a pixel portion is provided; a wiring formed over the first substrate and outside the pixel portion, the wiring comprising a first portion, a second portion, and a third portion; an EL element over the first substrate, the EL element comprising an EL layer interposed between a first electrode and a second electrode; a second substrate over the EL element, wherein the second substrate is bonded to the first substrate with an adhesive, wherein the second substrate opposing the first substrate comprises a first thickness at a first region and a second thickness at a second region, the first region adhering to the first substrate with the adhesive, and the second region is located inside the first region and depressed relative to the first region, wherein the first portion of the wiring is located under the second region and electrically connected to the second electrode, wherein the second portion of the wiring is located under the first region and interposed between the adhesive and the first substrate, wherein the third portion of the wiring is located outside the first region, and wherein a part of the first portion of the wiring is covered with the second electrode.
