Method of manufacturing display panel, and supporting bed for substrate of the display panel

Abstract

A method of manufacturing display panels includes the steps of forming a material layer on a substrate (23), and baking the material layer formed on substrate (23) which is placed on a supporting bed (20). The supporting bed (20) is formed of a first supporting bed (21) and a second supporting bed (22) placed on the first one (21). A difference in thermal expansion coefficient between the second supporting bed (22) and the substrate (23) is set smaller than a difference in thermal expansion coefficient between the first supporting bed (21) and the substrate (23), and the substrate (23) is placed on the second supporting bed (22) such that the second supporting bed (22) exists around the substrate (23) during the baking step for being heated and baked. This structure allows suppressing the production of scratches on a surface of the substrate (23).
