An optical disc manufacturing method includes: an injection step of injecting a liquid material into a circular plate-shaped injection space having a center hole portion at a center from an injection hole connected to an inner edge portion in the injection space; a discharge step of discharging air and the liquid material from a discharge hole formed on a straight line passing through the injection hole and a center of the center hole portion in a plane direction of the circular plate and at a position opposite to the injection hole; a curing step of curing the liquid material injected into the injection space; and a takeout step of taking out the cured liquid material from the injection space.

Optical disc manufacturing method

A recording method whereby an inorganic resist made of an incomplete oxide of a transition metal is formed as a film onto a substrate and a latent image corresponding to pits is formed onto the inorganic resist by exposure. The exposure is performed by a laser beam whose intensity has been modulated by a pulse signal whose pulse height decreases in a rear portion in a length direction of the pit, thereby forming a format of a track pitch smaller than a recording beam diameter (track pitch/exposure beam diameter=0.333 to 0.833).

High density optical disc having small track pitch

An electrodeposition display panel manufacturing method capable of manufacturing a highly reliable display panel in a short time and effectively, an electrodeposition display panel, and an electrodeposition display device are provided. Openings (A), (B) are provided in a rear substrate () of the cell. A nozzle (A) to which an injector () is connected on the other side is inserted into the opening (A), and a nozzle (B) is inserted into the opening (B). On the other end side of the nozzle (B), a container for recovering a spilled display material () and a decompressor are arranged. While the display material () is pressure-injected from the opening (A), evacuation and discharging air bubbles and the like are performed from the opening (B). Thereby, the display material () is filled in the cell.
