Abstract
A display device can be reduced in size while suppressing evenness in luminance. An image forming apparatus having such a display device incorporated therein is also provided. A driving unit drives a liquid crystal. A first member and a second member are disposed in opposition to each other with the liquid crystal interposed therebetween. The first member has a display area, and the second member has a display corresponding area corresponding to the display area of the first member and a non-display corresponding area which is different from the display corresponding area. A source of light is disposed within the non-display corresponding area of the second member. A guide member is disposed at a side of the second member opposite the first member for guiding light from the source of light.
