Method of manufacturing liquid crystal panel using etching to form microlenses, a heat resisting porous substrate, or a barrier film preventing sodium diffusion

摘要

A first glass substrate which is in contact with a liquid crystal layer is etched from its outer face. In this case, a panel to be etched is disposed on a susceptor with the first glass substrate being directed toward a shower head. The etching is carried out by uniformly spraying etchant from the shower head onto a face of the glass substrate.
