Abstract: An optical substrate is manufactured such that a bright color display can be achieved. The optical substrate can be embodied in a display device. As for the optical substrate, a light transmitting layer is formed by bonding a first master having a plurality of color protrusions and a second master having a plurality of curved surface parts with a light transmitting layer precursor disposed therebetween so that the resulting light transmitting layer has a plurality of color recesses transferred from the shape of the color protrusions and a plurality of lenses transferred from the shape of the curved surface parts. The master is separated from the light transmitting layer. The color recesses in the light transmitting layer are filled with pigment to form a color pattern layer. The second master is separated from the light transmitting layer.
Abstract: The present invention relates to the electrophoretic separation of bio-organic molecules using a slab gel electrophoresis apparatus having a pair of spaced, confronting plates defining a multi-lane separation zone adapted to hold a separation medium and an upper loading zone. In one aspect of the invention, at least one of the plates is shaped to provide an expanded loading zone. The plate-to-plate distance within the expanded loading zone is greater than the plate-to-plate width within the separation zone. In another aspect of the invention, a comb is provided with each tooth having a gradual taper beginning at a support member and extending along most of the tooth's longitudinal axis, and a sharp taper beginning immediately beyond the gradual taper and extending to the end of the tooth.
