PROBLEM TO BE SOLVED: To prevent contamination of equipment in different manufacturing processes such as a conveyance carrier and a clean room by completely eliminating powered matters generated by chemical etching for the purpose of making a display panel thin. SOLUTION: First, a display panel is produced by connecting a pair of substrates having a prescribed thickness with a prescribed gap between the substrates with the pair of the substrates overlapped. Next, the internal display panel is sealed hermetically along the outer circumferential parts of the both substrates by supplying a sealing material to the outer circumferential parts of the substrates. After that, the substrates are soaked in chemicals while protected with the sealing material, and the surfaces of the substrates are removed by a fixed quantity by chemical reaction to make the substrates thin. The sealing material is dried after washing the substrates, and powered matters generated by the chemical reaction are deposited at the outer circumferential parts of the substrates. The substrates are washed again to eliminate the powered matters and are then dried.
