摘要： A photosensitive sheet favorably employable for covering a pixel sheet is composed mainly of a support and a photosensitive colored resin layer containing a dye whose color disappears by application of heat or light. The coverage of the pixel sheet can be performed by combining the pixel sheet and the photosensitive sheet which has been examined for checking evenness of the surface of the colored resin layer under the condition that the pixels are brought into contact with the colored resin layer to give a combined body; separating the support of the photosensitive sheet from the combined body, leaving the colored resin layer on the pixel sheet; exposing to light the photosensitive colored resin layer on the pixel sheet so as to cure the photosensitive colored resin layer and possibly to make the resin layer colorless; and heating the light-exposed colored resin layer so that the colored resin layer is made colorless or the curing further proceeds.
