Abstract: A light control member includes a light control substrate including a surface, and a scalene prism disposed on the light control substrate. The scalene prism includes a first side surface extended at a first angle with respect to the surface of the light control substrate, and a second side surface extended at a second angle with respect to the surface of the light control substrate, the second angle being greater than the first angle. The light control member includes an etching stopper disposed on the scalene prism, and at least one absorption pattern disposed on the etching stopper on the second side surface of the scalene prism.
