Abstract: A stage on which a substrate having target discharge areas is placed moves relative to a discharge head unit. When at least one of a plurality of first discharge nozzles of the discharge head unit reaches one of the target discharge areas, the first nozzle discharges a first droplet of fluid material to the target discharge area. When one of a plurality of second nozzles of the discharge head unit reaches the target discharge area to which the first droplet has been discharged, the second nozzle discharges a second droplet of the fluid material to the target discharge area. A first nozzle row of the first nozzles and a second nozzle row of the second nozzles are separated by a predetermined distance in a direction of the relative movement of the stage and the discharge head unit.

A manufacturing method of a color display substrate includes the step of forming plural color dots by selectively ejecting liquid droplets from nozzles in accordance with input data. The plural color dots constitute plural pixels, which constitute plural color filter elements arranged in a matrix pattern. The plural color dots have a first dot pitch in a direction perpendicular to a first base line. Each of the plural color dots is formed to lie at a distance of at least substantially an integral multiple of the first dot pitch from the first base line.

Abstract: A display apparatus is provided with a current driving type light-emitting device and a driving device for controlling a driving current flowing through the light-emitting device for each pixel of the display apparatus. The display apparatus consists of power source units for supplying power for causing a driving current to flow via the driving device to the light-emitting device via a power source wire, and signal wire driving units for supplying a data signal to the driving device via signal wires. In addition, voltage adjusting units adjust a voltage for the power source units or a data signal from the signal wire driving units so that a quantity of a driving current flowing through the light-emitting device when a data signal of a predetermined voltage is supplied to the driving device via signal wires or a quantity of emitted light emitted from the light-emitting device comes close to a predetermined reference value.

Abstract: In the discharge apparatus, a stage on which a substrate having target discharge areas is placed moves relative to a discharge head unit. When at least one of a plurality of first discharge nozzles of the discharge head unit reaches one of the target discharge areas, the first nozzle discharges a first droplet of fluid material to the target discharge area. When one of a plurality of second nozzles of the discharge head unit reaches the target discharge area to which the first droplet has been discharged, the second nozzle discharges a second droplet of the fluid material to the target discharge area. A first nozzle row of the first nozzles and a second nozzle row of the second nozzles are separated by a predetermined distance in a direction of the relative movement of the stage and the discharge head unit.

Abstract: The invention mitigates a drop of a protective layer and reduces disconnection of an electrode. A shading layer, a partition layer to partition a color filter layer, formed on the shading layer, and a protective layer to seal the shading layer, the partition layer and the color filter layer, are arranged on a substrate. At least a part of the partition layer covers the shading layer and separates the protective layer from the shading layer under a non-contact state.

Abstract: A donor sheet for transferring an image pattern to an image receiving element by a thermal imaging process using laser beam, comprising a base having formed in order on the base a light-to-heat conversion layer, and a transfer layer containing an image component which is melted by heating due to an action of the light-to-heat conversion layer and transferred to the image receiving element in a patterned form, in which the image component of the transfer layer contains an ink-repellent or solvent-repellent compound in an optimized amount. Using the donor sheet, it becomes possible to produce an separation member such as partition pattern and black matrix of a color filter by a shortened manufacturing step with ease and accuracy at high contrast, and can impart excellent ink repellency to the separation member.

Abstract: A color filter (200) comprises pixels (13) separated from each other by partitions (14) formed on a substrate (12) so as to have a plurality of color elements of ink. Dummy pixels (13?) are formed outside the area in which the pixels (13) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film (21) covering said pixels (13) is formed so as to also cover said dummy pixels (13?).
