ABSTRACT:
A liquid display device of D-STN mode capable of suppressing a line-shaped ununiformity of brightness in displaying a dark appearance is presented. A displaying cell1and a compensation cell21are formed so that there is a difference of thickness of at least 0.05 mm between the thickness of a glass substrate2at a front side of the displaying cell1and the thickness of a glass substrate at a rear side of the compensation cell21. The displaying cell1and the compensation cell21are arranged between a first polarizing plate32and a second polarizing plate33. A backlight31is of a type emitting light whose half value width with respect to the peak luminance is at least 5 nm.
