Zusammenfassung:	An ultrasound diagnostic apparatus (200) is provided that includes: a probe (210) that receives an ultrasound signal reflected off an object; a processing unit (260) that generates image information based on the ultrasound signal; and a liquid crystal display (270) that displays the image information, wherein the liquid crystal display includes: a liquid crystal panel (110) including a pair of substrates (113, 114) arranged in an opposing manner and a liquid crystal layer (115) sandwiched between the pair of substrates; a pair of polarizing plates (111, 112) arranged on a light source side and a display surface side, respectively, of the panel and forming crossed Nicol prism; a first optical element (120) in which a light-blocking layer and a light-transmitting layer are alternately and continuously arranged in a planar direction, the first optical element (120) being arranged between the polarizing plate on the light source side and the light source; and a second optical element (130) having a surface scattering function arranged on the polarizing plate on the display surface side, and the first optical element is arranged such that a major axis of the light-blocking layer that is an axis extending in a light-transmitting direction is oriented in a direction determined based on at least one of the crossed Nicol prism and the second optical element.
