摘要： A video image evaluation equipment of the present invention is capable of converting circularly-polarized light emitted from a circularly polarizing light source into linearly-polarized light so as to transmit an absorption-type linear polarizer by a wavelength plate to be incident on a liquid crystal panel. This makes it possible to enter and reflect light emitted from the circularly polarizing light source on the liquid crystal panel without loss, which leads to display brighter video images than conventional ones.

摘要： A method for fabricating a glass substrate for an information recording medium ensures removal of an abrasive or foreign mater adhered to the glass substrate after a polishing step, and involves, after the polishing step, keeping the surface of the glass substrate in contact with a liquid for 10 minutes or more before a scrub-cleaning step. To ensure that the abrasive or foreign matter firmly adhered to the glass substrate is removed by scrub-cleaning, preferably, the surface of the glass substrate is kept in contact with the liquid with the glass substrate immersed in the liquid which is collected.
