Patent ID: 7704650

Claim:
A method of producing a color filter comprising a transparent substrate, a plurality of picture elements disposed on a predetermined position of the substrate, and a partition pattern for separating adjacent picture elements, which comprises the steps of: forming a thin film-like black matrix in a predetermined pattern on the surface of the substrate; making the surface of the black matrix side of the substrate and a transfer layer of a donor sheet comprising a base, a light-to-heat conversion layer, and the transfer layer containing an image component which is melted by heating due to an action of the light-to-heat conversion layer and transferred to the substrate in a patterned form, said layers being formed in order on the base, come closely into contact with each other; irradiating laser beam from the base side of the donor sheet corresponding to the pattern of the black matrix by a thermal image process using laser beam, thereby to melt the image component of the transfer layer of the donor sheet with heating and to pile up the molten image component on the black matrix; and filling an opening portion surrounded by the formed partition pattern with ink having a predetermined color using an ink-jet method.
