Abstract: 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.

Abstract: Photomasks used for sandblasting and sandcarving may be readily produced by the user of the photomask in a simple and relatively inexpensive manner. The user places a stencil and print positive in a manual clamping structure --between a pivoted glass cover and foam covered base and exposes them to about 60-90 seconds of ultraviolet light from a 500 watt bulb. After removing the print positive, the stencil is then placed on a support surface above a tank, and reciprocating spray heads direct 100 psi, 90 degrees F. water onto the stencil to remove uncured emulsion. A combination pump/heater within the tank recirculates tank water to the spray heads. The stencil is then hand blotted, e.g. using a lamb's wool roller, and then dried in a microwave oven at low power for about eight minutes. Then it is placed on newspaper, and hat activated liquid adhesive is placed in a pool at one end of it and manually drawn over it with a draw bar, to produce the final photomask.
