Abstract:
1. An in-plane-switching-mode liquid crystal display (IPS LCD) device comprising: a liquid crystal (LC) layer having a first refractive index; a light-incident-side substrate and a light-emitting-side substrate sandwiching therebetween said LC layer; and a light-incident-side polarizing film and a light-emitting-side polarizing film sandwiching therebetween said substrates and said LC layer, said light-incident-side substrate including a substrate body having a second refractive index and an insulation layer overlying said substrate body and having a third refractive index which is higher than said first and second refractive indexes, said insulation layer having a thickness (d nm) substantially satisfying the following relationship: where k is an integer not smaller than zero and not larger than 5.
