Liquid drop discharge method and discharge device; electro optical device, method of manufacture thereof, and device for manufacture thereof; color filter method of manufacture thereof, and device for manufacturing thereof; and device incorporating backing, method of manufacturing thereof, and device for manufacture thereof

An electro optical device comprising a substrate and color filters of various colors, which are formed on the substrate, and are made by using a plurality of discharge means and a holding means on which said plurality of discharge means are mounted, wherein

• each of the discharge means comprises a liquid drop discharge head which is provided with nozzles which discharge liquid mass including a material for the color filter of predetermined color, a mounting board on which said liquid drop discharge head is mounted, and a connector which is arranged on said mounting board;
• said plurality of discharge means are aligned so as to be separated into groups of discharge means, and are orientated so as not to face the connector in one of groups to the discharge means in the other of the groups, and
• said liquid drop discharge head discharges a predetermined amount of the liquid mass to predetermined positions of the substrate so as to form said color filters while moving relative to the substrate plate by said holding means in a state where a plane on which said nozzles are arranged faces to a surface of the substrate plate at a predetermined distance.

Color filters which are formed so as to generate various colors on a substrate, and are made by using discharge means each of which comprises a liquid drop discharge head in which a nozzle which discharges liquid mass comprising various colors of materials for color filters and a holding means on which said discharge means are arranged, wherein

• each of the discharge means comprises a liquid drop discharge head which is provided with nozzles which discharge liquid mass including a material for the color filter of various colors, a mounting board on which said liquid drop discharge head is mounted, and a connector which is arranged on said mounting board;
• said plurality of discharge means are aligned so as to be separated into groups of discharge means, and are orientated so that the connectors in one of the groups do not face the discharge means in the other of the groups, and
• said liquid drop discharge head discharges a predetermined value of the liquid mass to predetermined positions of the substrate so as to form said filters while moving relative to the substrate plate by said holding means in a state where a plane onto which said nozzles are arranged faces to a surface of the substrate at a predetermined distance.

A method of discharge liquid mass by using a holding means and a plurality of discharge means which are mounted on said holding means, wherein

• is provided with nozzles which discharge liquid mass having a certain flowability, a mounting board on which said plurality of nozzles are mounted, and a connector which is arranged on said mounting board,
• said plurality of discharge means are aligned so as to be separated into groups of discharge means, and are orientated so that the connectors in one of the groups do not face the discharge means in the other of the groups, and
• said liquid drop discharge head discharges a predetermined amount of the liquid mass to predetermined positions of the object onto which the liquid mass is discharged while moving relative to the object onto which liquid drops are discharged by said holding means in a state where a plane onto which said nozzles are arranged is directed along a surface of the substrate plate.

A device comprising a substrate and a predetermined layer which is formed by discharging a liquid mass having a certain flowability to said substrate and is made by using a plurality of discharge means and a holding means on which said discharge means are mounted, wherein

• each of said discharge means comprises a liquid drop discharge head which is provided with nozzles which discharge liquid mass including an electro-luminescent material, a mounting board on which said liquid drop discharge head is mounted, and a connector which is arranged on said mounting board;
• said plurality of discharge means are aligned so as to be separated into groups of discharge means, and are orientated so that the connectors in one of the groups do not face the discharge means in the other of the groups, and
• said liquid drop discharge head discharges a predetermined amount of the liquid mass to predetermined positions of the substrate so as to form said predetermined layer while moving relative to the substrate by said holding means in a state where a plane on which said nozzles are arranged is directed along a surface of the substrate.
