The present invention is a method of producing a multicolor pixel sheet on which pixels of different colors (R, G and B) and a black matrix are formed. Pixels are formed with a gap therebetween on a light-transmitting substrate and each pixel is composed of a coloring layer. The black matrix is formed by a black coloring resin provided at upper surfaces of pixels on the pixel sheet, the gap between the pixels, and the outer periphery defined by the outermost pixels. A two-stage developing process is conducted after exposure from the back and the front of the substrate to form a spacer pattern having a predetermined thickness on the black matrix.
