Abstract:
1. A semiconductor device comprising: a first substrate; a pixel portion comprising a first source line, a second source line and a third source line, and over the first substrate; a D/A converter circuit over the first substrate; a first switch between the D/A converter circuit and the first source line; a second switch between the D/A converter circuit and the second source line; a third switch between the D/A converter circuit and the third source line; a second substrate over the pixel portion; a first sealing material interposed between the first substrate and the second substrate, and surrounding the pixel portion, the first switch, the second switch and the third switch, and a second sealing material formed outside of the first sealing material, wherein the second sealing material is in contact with at least a side surface of the second substrate, and wherein the first switch, the second switch and the third switch turn on sequentially and alternately.
