A liquid crystal elemental device comprising a pair of substrates arranged in opposed relation to each other through a spacer and a liquid crystal held in a space between the substrates is produced by applying a spacer-forming material onto one of the pair of substrates by an ink-jet system to form the spacer, arranging the pair of substrates in opposed relation to each other with the spacer held therebetween, and enclosing a liquid crystal compound in the space between the pair of substrates.

A method for making a color filter substrate includes the steps of: forming barriers on a substrate; placing an ink having a surface tension of 20 to 60 dyne/cm onto regions between the barriers; and curing the ink to form color filters. The volume of the ink charged onto one region is three to ten times the volume of the region. A color filter substrate is produced by the above-mentioned method. A liquid crystal device includes a pair of substrates and a liquid crystal encapsulated between the pair of substrates, wherein one of the pair of substrate is the above-mentioned color filter substrate.

A method for forming spacers according to the present invention is a method for forming the spacers on a substrate, comprising the steps of: supplying adhesive at a position for forming each of the spacers on the substrate by an inkjet system; dispersing beads, each bead having a diameter corresponding to the height of the spacer, so as to adhere the beads to adhesive; and removing the beads that are not adhered to the adhesive from the substrate. A manufacturing method for a color filter having spacers according to the present invention, the method comprises the steps of: forming a color filter by forming on a substrate at least a light-shielding layer having plural apertures and a colored layer having colored portions arranged in each of the apertures of the light-shielding layer; supplying adhesive made of a curable resin composition in regions overlapping the light-shielding layer on the color filter by an inkjet system; dispersing beads on the color filter so as to stick the beads to the adhesive; and removing the beads that are not adhered to the adhesive from the color filter. Furthermore, a liquid crystal element according the present invention comprises: a pair of substrates; and liquid crystal clamped between the pair of substrates, wherein one of the pair of substrates is a color filter having spacers made by the above-mentioned manufacturing method and the distance between the pair of substrates is maintained by the spacers.

摘要:
A color filter manufacturing method comprises the steps of forming, on a substrate, a photosensitive layer that increases or develops hydrophilic property upon irradiation of light; exposing the photosensitive layer to light for patterning to form hydrophilic areas in which hydrophilic property is relatively high and non-hydrophilic areas in which hydrophilic property is lower than the hydrophilic areas; and applying a setting ink to the hydrophilic areas with an ink jet technique, thereby forming colored portions. A color filter includes at least a photosensitive layer formed on a substrate and having hydrophilic areas in which hydrophilic property is increased or developed upon irradiation of light, and colored portions formed on the hydrophilic areas of the photosensitive layer. A liquid crystal device is constructed by using the color filter. The color filter can be manufactured inexpensively with the reduced number of steps while satisfying requisite characteristics. Color mixing, color unevenness and uncolored dots are prevented and a highly reliable color filter is provided.
