Patent ID: 7525632

Claim:
A liquid crystal display (LCD) device comprising: an LCD panel including two substrates and a liquid crystal layer formed between the two substrates to display an image, and a backlight formed on a rear surface of the LCD panel to provide light, wherein the liquid crystal layer includes liquid crystal properties that are optimized for a driving temperature of the LCD panel between about 30° C. and about 70° C.; and wherein the liquid crystal layer includes a multiplication (Δnd) of a cell gap (d) and a refractive anisotropy (Δn) that are determined in a range of between 300 nm and 340 nm at the driving temperature, and wherein the liquid crystal layer includes a ratio of a refractive anisotropy Δn at a temperature of 20° C. to a refractive anisotropy Δ n at a substantial driving temperature of the LCD panel (Δn (20° C.) /Δn (driving temperature T) ) within a range of 0.9 and 1.
