Abstract: PROBLEM TO BE SOLVED: To reduce the weight and thickness of a display panel without lowering productivity. SOLUTION: The display panel is formed by first performing a panel forming process step in order to manufacture the display panel, flatly shifting a pair of substrates 1 and 2 having a prescribed thickness by a prescribed amount from each other, superposing these substrates and joining a pair of the substrates 1 and 2 across a prescribed spacing in the state of providing the outer peripheries of both substrates 1 and 2 with a step ST along the outer peripheries. In succession, an outer periphery sealing process step is performed and a sealant is supplied to the step ST, by which the display panel of the interior is hermetically closed along the outer peripheries of both substrates 1 and 2. The chemical treatment process step is thereafter performed and the display panel is immersed into a liquid chemical in the state that the panel is protected by a sealant and the surfaces of the substrates 1 and 2 are removed by the specified amount by chemical reaction, thereby, the thickness is reduced. When a pair of the substrates are bonded to each other by shifting the substrates from each other, the since step ST is formed along the outer periphery this part can be stably and easily coated with a sealant by a dispenser 50, The sealant with which the step ST is coated along the same infiltrates the spacing between both substrates 1 and 2 by capillarity and the perfect outer peripheries seal can be formed.

Abstract: PROBLEM TO BE SOLVED: To provide a display device capable of preventing a short circuit from occurring in a metallic frame, and to provide a manufacturing method therefor. SOLUTION: A liquid crystal 24 is filled in a space formed between an active substrate 21 and a counter substrate 22. On the surface of an overcoat layer 29 of the counter substrate 22, an ITO film 12 is formed as a conductive film to be used as an electrode layer to the inside at predetermined intervals away from the circumferential parts of a glass substrate 27 and the overcoat layer 29. Even if burrs are produced on the glass substrate 27, the overcoat layer 29, or the like on the counter substrate 22 and come into contact with a metallic frame 32, the ITO film 12 as the electrode layer is not brought into direct contact with the metallic frame 32 and the short circuit is avoided.
