Patent ID: 10386569

Abstract:
Provided is an optical member having a high brightness, a low haze, and a small color change, an optical element, a liquid crystal display device, and a near-to-eye optical member. The optical member includes a plurality of cholesteric liquid crystal dots that are provided on a substrate, in which a shape of each of the dots is a hemispherical or elliptical hemispherical shape in which the substrate side is planar, a conical or elliptical conical shape in which the substrate side is set as the bottom, or a shape in which a plurality of shapes selected from the shapes are laminated, the cholesteric liquid crystal dot has a reflection center wavelength with respect to visible light, the cholesteric structure of the dot has a stripe pattern including bright portions and dark portions in a cross-sectional view of the dot when observed with a scanning electron microscope, the dot includes a portion having a height which continuously increases to a maximum height in a direction moving from an end portion of the dot to the center of the dot, and in the portion, an angle between a normal line perpendicular to a line, which is formed using a first dark portion from a surface of the dot opposite to the substrate, and the surface of the dot is in a range of 70° to 90°.
