Patent ID: 7072013

Claim:
A liquid crystal display device, comprising: a first substrate having an inner surface and an outer surface; a second substrate having an inner surface and an outer surface, wherein the inner surface of the second substrate faces and is faced apart from the inner surface of the first substrate; a retardation film arranged on the inner surface of the second substrate; a second polarizing film arranged on the retardation film; a first polarizing film on the outer surface of the first substrate; a layer of liquid crystal material arranged between the first and second substrates; a backlight unit proximate to the outer surface of the second substrate; a cholesteric liquid crystal polarizing film arranged between the second substrate and the backlight unit, wherein the cholesteric liquid crystal polarizing film includes a first portion adjacent to the backlight unit, a second portion adjacent to the outer surface of the second substrate, and a third portion between the first and second portions, wherein the first portion includes a first pitch, wherein the second portion includes a second pitch, wherein the third portion includes a third pitch, wherein a value of the third pitch is between values of the first and second pitches.
