Abstract: A liquid crystal display device according to one aspect of the present invention includes a liquid crystal panel of a vertical alignment mode, and an optical control member disposed on a light-exiting side of the liquid crystal panel. The liquid crystal panel includes a plurality of pixels having at least two domains (50a, 50b), in which directors of liquid crystal molecules are in a first direction. An absorption axis of a first polarizing sheet and an absorption axis of a second polarizing sheet are a mutually orthogonal and form angle that is approximately 45°. The optical control member includes a base, a light diffusion part, a light blocking layer and a low refractive index part. A planar shape of the light blocking layer (40) when seen from a normal line direction of the base has a straight line part parallel to the absorption axis (P1, P2) of one of the first polarizing sheet and the second polarizing sheet and a straight line part forming an angle of less than 45° with the absorption axis (P1, P2) of one polarizing sheet.
