The present invention provides a liquid crystal display device which can decrease lowering of light utilization efficiency attributed to a light absorption axis of an alignment film. A liquid crystal display device includes a liquid crystal display panel and a backlight arranged on a back surface of the liquid crystal display panel. The liquid crystal display panel includes liquid crystal, and a first substrate and a second substrate arranged to face each other in an opposed manner with the liquid crystal therebetween. The first substrate is arranged between the second substrate and the backlight. The first substrate includes a first polarizer and a first alignment film arranged between the first polarizer and the liquid crystal. The second substrate includes a second polarizer and a second alignment film arranged between the second polarizer and the liquid crystal. The second alignment film has a light absorption axis, and an angle made by the light absorption axis of the second alignment film and a light absorption axis of the second polarizer is set to a value which falls within .+-.1.degree.. The first alignment film has a light absorption axis, and an angle made by the light absorption axis of the first alignment film and a light absorption axis of the first polarizer is set to a value not less than 89.degree. and not more than 91.degree.. (degree of polarization of the first alignment film)/(degree of polarization of the second alignment film) is set to a value not more than 0.9.
