In a method of producing a condenser lens substrate, after a first clear substrate and a second clear substrate where a micro-lens having a spherical surface or a lenticular lens is formed are stuck to each other, at least one of the clear substrates is ground. At this time, the clear substrate is ground so as to have a thickness that a focus of the micro-lens or the lenticular lens is positioned in the vicinity of the outer surface of the first or the second clear substrate. This makes it possible to form a micro-lens or a lenticular lens having a short focus in a substrate of a liquid crystal display element. As a result, when a condenser lens substrate is produced, a possibility of breakage of the clear substrate is eliminated, and handling and sticking of clear substrates become easy, thereby making it possible to improve mass-productivity of a condenser lens substrate.
