Provided is a light transmissive stamper which does not generate a residue of a curable resin even when the stamper including a support substrate and an inorganic resist is used to mold a substrate. The light transmissive stamper is used when an information pattern of an optical recording medium is formed using a curable resin. The light transmissive stamper includes a light transmissive support substrate, a light transmissive inorganic resist layer having an uneven pattern corresponding to an information pattern formed therein, and a peeling layer provided on a side surface of the light transmissive stamper and having a higher peelability from the curable resin than a peelability from the light transmissive support substrate.

A color filter comprising a substrate, a shielding layer formed on the substrate and having an opening, color mixing prevention barriers formed on the shielding layer, and colored portions formed between the color mixing prevention barriers, the optical density of the colorants in the colored portions being raised toward the substrate.

Color filter and method of manufacturing the same

In a method of manufacturing a color filter, an ink-jet head discharges ink onto a substrate formed on a surface of an ink receiving layer and colors each pixel of the color filter. The ink-jet head discharges ink onto the position of each pixel by using an alignment mark as a reference which is formed on the ink receiving layer.

Color filter manufacturing method, color filter, display apparatus, and apparatus having the display apparatus

A color filter substrate manufacturing method includes the steps of forming a black matrix having a plurality of first apertures of the same shape on a support substrate, forming a color filter by an ink jet system, and forming an alignment mark within an effective display region. The alignment mark includes a second aperture different in shape from the first apertures of the black matrix and is used to form the color filter.

Color filter substrate manufacturing method, color filter substrate

Disclosed herein is a process for producing a color filter substrate, which comprises the steps of forming a resin layer for coloration, which develops an ink-accepting property by irradiation of light, on a base; forming a light-screening layer on the resin layer for coloration; exposing the resin layer for coloration through the light-screening layer as a mask; and applying color inks to the resin layer for coloration.

Production of color filter by forming light-screening layer and

The optical recording medium has an optically transparent substrate having a center hole, a recording layer formed on the substrate, and a protective layer. The protective layer has an opening whose center coincides with a center of the center hole of the substrate, and the opening of the protective layer is larger than the center hole of the substrate. The optical recording medium is produced by a process including the steps of forming the protective layer for covering the recording layer so that the protective layer has an opening whose center coincides with a center of the center hole, and forming the opening of the protective layer so that it is larger than the center hole of the substrate. The step of forming the protective layer may be achieved using a spin coating method.
