MANUFACTURE OF COLOR FILTER

摘要

PURPOSE:To enhance the transfer efficiency of a picture element and to obtain superior spectral diffraction and chromaticity characteristic by imparting an electric charge with polarity opposite to that of color toner from the back side of a filter substrate facing to the picture element, and transferring the picture element on a picture element plane on the filter substrate. CONSTITUTION:An electrostatic latent image can be formed by electrifying a light conductive layer 3 at ground 200V from the picture element side of a transfer supporting body 1 and exposing it via the light shielding mask of a picture element pattern after electrification is completed. After the electrostatic latent image is formed, developing is applied to it, and the picture element 5 is accomplished as a transfer material. After that, the electric charge with same polarity as that of the electrified charge of the toner is imparted by a corona electrifier 6. Thence, the filter substrate 4 is superimposed setting the picture element side of the transfer material at inside via the picture element 5, and the electric charge with polarity in the direction opposite to that of the electrified charge of the toner of the picture element 5 is imparted from the supporting body from the opposite side of the picture element by the corona electrifier 6. After electrification is completed, the filter substrate 4 is peeled from a transfer substrate, and electrostatic transfer on the filter substrate 4 from the transfer substrate of the picture element 5 can be completed.
