A display apparatus includes: a pixel part including a plurality of pixels arranged substantially in a matrix form, where the matrix form includes a unit matrix having X columns in a horizontal direction and Y rows in a vertical direction, where X and Y are natural numbers; and a plurality of light controlling parts inclined with respect to the vertical direction of the pixels on the pixel part at an inclined angle of θ, where the inclined angle of θ satisfies the following equation: θ=tan−1((M×X)/(N×Y)), where M and N are different natural numbers.
