    摘要: Disclosed are active shutter glasses and a three-dimensional image recognition unit capable of visually recognizing a three-dimensional image with excellent display quality. The active shutter glasses are active shutter glasses for three-dimensional image recognition. The active shutter glasses comprise a right temple, a left temple, a right-eye lens, and a left-eye lens. The right-eye lens and the left-eye lens comprise liquid crystal cells. The right-eye lens and the left-eye lens have an inclination with respect to a state where the right-eye lens and the left-eye lens are arranged on the same plane, and are arranged on a surface orthogonal to a horizontal surface including the top surfaces of the right temple and the left temple. The direction of inclination of the right-eye lens is the direction in which the outer edge of the right-eye lens approaches an observer side at an azimuth angle Æ 2 in a range of ±45° with respect to an azimuth angle Æ 1 , at which a contrast ratio has a maximum value, at a polar angle ¸ 1 having an angle difference in a range of 2 to 17° from a line normal to the surface of the right-eye lens when not inclined. The direction of inclination of the left-eye lens is the direction in which the outer edge of the left-eye lens approaches the observer side at an azimuth angle Æ 4 in a range of ±45° with respect to an azimuth angle Æ 3 , at which a contrast ratio has a maximum value, at a polar angle ¸ 2 having an angle difference in a range of 2 to 17° from a line normal to the surface of the left-eye lens when not inclined.
