Patent ID: 8659516

Claim:
A display device comprising: a first substrate; a pixel portion over the first substrate; a source driver circuit over the first substrate, the source driver circuit comprising: a first circuit comprising an op amp; a second circuit comprising a latch circuit, wherein an output of the second circuit is operationally connected to an input terminal of the first circuit, a first line electrically connected to the pixel portion, wherein the first line is operationally connected to an output terminal of the first circuit; a second substrate over the first substrate with the pixel portion, the source driver circuit, and the first line interposed therebetween; a first sealing material interposed between the first substrate and the second substrate, wherein the first sealing material is disposed along peripheries of the first and second substrates; and a second sealing material formed outside of the first sealing material, wherein the second sealing material is in contact with side surfaces of the first and second substrates, wherein both the first sealing material and the second sealing material surround the pixel portion.
