PURPOSE:To improve resolution and quality of a picture while forming an adhesive layer thinly and uniformly by supplying adhesives on a color resolving filter forming surface followed by making a thin plate glass sheet to adhere with pressure while being heated. CONSTITUTION:A hardening agent is added into epoxy resin and stirred to regulate adhesives followed by removing bubbles in said adhesives by means of vacuum defoaming and removing it into a microcylinder 8. On the other hand, the other side of a face plate 1 made of glass coated by a color resolution filter 2 on one side is set on a flat pressing frame 7. A proper quantity of adhesives 3 is dropped from the microcylinder 8 on said filter surface followed by laminating a thin plate glass sheet 4 having the thickness of about 30mum thereon. Thereafter, the thin plate glass sheet 4 is pressed on the filter surface vertically to said plate surface for adhering by means of a jig 9 heated up to 35-140 deg.C followed by further putting said face plate composite into a heating furnace to be heated at about 70 deg.C for about three hours for hardening the adhesives 3.
