ABSTRACT:
A method of making a color filter includes the steps of bringing a color film sheet provided with a heat-fusible color dye layer into close contact with a support, and heating the color film sheet to transfer the color dye layer onto the support. The color film sheet further includes a light-heat conversion layer and a base film deposited under the color dye layer, and a separating layer provided between the base film and the color dye layer. Alternatively, the color film sheet further includes a base film and a light-heat conversion layer deposited under the color dye layer, and a stress-relieving layer provided between the base film and the color dye layer.
