Abstract: A display device includes a first substrate on which gate lines and data lines are disposed; a second substrate facing the first substrate; a pixel disposed between the first substrate and the second substrate, and connected to the gate line and the data line; a light blocking layer disposed between the first substrate and the second substrate, and defining a light emission area of the pixel; a polarizer on the second substrate; and a first pattern layer disposed on the polarizer, and comprising a plurality of first protruding portions. The number of first protruding portions that overlap the light emission area among the plurality of first protruding portions is in a range from 3 to 15. An angle between the data line and each of the plurality of first protruding portions is in a range from about 5 degrees to about 10 degrees.
