1. An image display system comprising: display means including a first display panel; a first polarizer located at a distance from a front surface of the display means; a second display panel provided to a front of the first polarizer; a second polarizer, having pixels, located at a distance from a front surface of the first display panel; a third polarizer located at a distance from a front surface of the second polarizer; and a fourth polarizer, having pixels, located at a distance from a front surface of the third polarizer, wherein the fourth polarizer has a pixel size that is the same as a pixel size of the pixels of the second polarizer, wherein each pixel of the second polarizer has a size of dividing a unit pixel of the display panel into two units and each pixel of the second polarizer is divided into a first unit and a second unit, wherein the first unit has a polarization state that is orthogonal to a polarization state of the second unit, wherein each pixel of the fourth polarizer is divided into a third and a fourth unit, and wherein the third unit has a polarization state that is orthogonal to a polarization state of the fourth unit.
