Abstract

PURPOSE:To rationalize a state and to permit cost reduction by forming a color filter on the 1st substrate, forming the color filter of the color different from the color of said color filter on the 2nd substrate and constituting an element in such a manner that the two color filters overlap on each other. CONSTITUTION:This element has the color filter 5 formed on the 1st substrate 1 and the color filter 6 which is formed on the 2nd substrate 2 and is of the color different from the color of the color filter 5 on the 1st substrate 1 and is so constituted as to have the part A where the color filters 5, 6 formed on the 1st and 2nd substrates 1, 2 overlap flatly on each other. The 3rd color mixed with 2 kinds of the colors is formed in the part A. The color display of the 3 colors is, therefore, made possible by two colors of the color filters formed on the upper and lower substrates 1, 2. The stage for forming the color filter is thereby rationalized and the cost reduction is made possible.
