A three-dimensional display panel includes an array of pixels arranged in row and column directions, and at least one lenticular lens configured to form N viewpoints in different directions. The at least one lenticular lens has a longitudinal axis inclined by an angle of with respect to a column direction of the pixel, and a pitch P of the at least one lenticular lens in the row direction thereof satisfies ( N S )  A < P < ( ( N + 1 ) S )  A , where N is the number of the viewpoints and is an integer greater than or equal to 1, S is the number of the lenticular lenses used to form the N viewpoints and is an integer greater than or equal to 1, and A is a width of each pixel in the row direction.
