The liquid crystal display device includes: a first polarizer having a first transmission axis; a liquid crystal panel; a second polarizer having a second transmission axis; a biaxial retarder having a slow axis parallel to the second transmission axis; a third polarizer having a third transmission axis parallel to the second transmission axis; and a backlight, a back side polarizer portion that includes the second polarizer, the biaxial retarder, and the third polarizer satisfying the following formula (1): ΔYI2=YI2′− YI2<0 (1) wherein YI2′ represents a yellowness index in observation from an oblique direction, YI2 represents a yellowness index in observation from a front direction, and ΔYI2 represents a difference between YI2′ and YI2, wherein the front direction represents a direction at a 0° polar angle and the oblique direction represents a direction at a 60° polar angle and a 45° azimuth.
A liquid crystal display device sequentially comprising from a viewing surface side to a back surface side:
