Abstract

A display device including: a first substrate with a pixel switch and drivers mounted thereon; a second substrate disposed in facing relation to the first substrate; a material layer held between the first substrate and the second substrate and having peripheral edges sealed by a seal member, the material layer having an electrooptical effect; and a semiconductor chip mounted as a COG component on the first substrate, the semiconductor chip having a control system configured to control the drivers; wherein the semiconductor chip having a thickness equal to the total thickness of the seal member and the second substrate or larger than the thickness of the seal member and smaller than the total thickness.

Claims (4)

1. A method of manufacturing a display device having a first substrate with a pixel switch and drivers mounted thereon, a second substrate disposed in facing relation to said first substrate, and a material layer held between said first substrate and said second substrate and sealed by a seal member, the method comprising:

a first step of mounting a semiconductor chip having a control system configured to control said drivers, as a COG component on said first substrate parallel to a region in which said seal member and said second substrate are stacked;

a second step of securing said first substrate and said semiconductor chip to each other; and

a third step of simultaneously polishing said second substrate and said semiconductor chip to the same thickness as each other.
