Display apparatus and display method thereof

A display method of a display apparatus comprising a display in which a plurality of pixels, each configured to be driven by an electrophoretic method, are in a pixel column unit, and a three-dimensional film divided into a plurality of refractive regions and on a plurality of pixel columns of the display, the display method comprising:

• displaying different content for each view of a plurality of vies by using pixels in the plurality of pixel columns within each refractive region of the plurality of refractive regions;
• and
• adjusting grayscale for each view of a plurality of view by performing dithering in units of a plurality of pixels consecutively in each pixel column of the plurality of pixel columns within each refractive region of the plurality of refractive regions.
