A liquid crystal color display device for displaying a color image represented by an applied image signal, including a liquid crystal cell, one or two polarizers, and a fluorescent light-emitting means. The liquid crystal cell and one polarizer disposed on one side thereof, or the liquid crystal cell and the two polarizers sandwiching the same, jointly constitute a switching element responsive to the image signal applied to the liquid crystal cell for passing electromagnetic radiation in a pattern representing the image given by the image signal. The fluorescent light-emitting means has a fluorescent layer and a lamp for generating electromagnetic radition, and may additionally include a color filter. The fluorescent layer is responsive to the electromagnetic radiation from the lamp for emitting chromatic fluorescent light. Where the fluorescent light-emitting means has the color filter, the fluorescent light passes through the color filter to display the image.
