<p>Provided is an operating device capable of preventing internal reflection of light from the exterior, and even correcting displacement of chrominance of display light from a display panel. Linearly polarized light (2) from a liquid crystal display panel (30) is converted to circular polarized light (3) at a ?/4 phase difference film (13), converted to linearly polarized light (4) at a ?/4 phase difference film (15) of an upper side, and is transmitted through a polarizing film (21). Light entering from the exterior is converted to circular polarized light (8) at the ?/4 phase difference film (15) of the upper side, is reflected at a lower portion conducting layer (14), whereupon the direction of rotation of the circular polarized light is reversed, and passes through the?/4 phase difference film (15) of the upper side to become linear polarized light (10). The optical axis of the linear polarized light (10) is perpendicular to the transmission axis of the polarizing film (21), whereby the linear polarized light (10) is prevented from returning to the exterior. A color correction layer (22) including a pigment or a dye on a side more external than the polarizing film (21) is provided. By selecting the pigment or dye and adjusting the amount thereof, even if the color displayed light is affected by the polarizing film, it is possible to correct the chrominance thereof.</p> |
