  • Patent number: 8235520
    Abstract: A droplet discharge device includes a stage, a droplet discharge head, a movement unit and a light radiating unit. The droplet discharge head includes nozzles arranged to discharge droplets of photo-curable liquid material toward a drawing region of a workpiece. The movement unit is arranged to move the stage and the droplet discharge head relative to each other. The light radiating unit has a light emitting part capable of emitting light to an entire area of the drawing region and disposed on a side opposite from the surface of the workpiece on which the liquid material is applied. The light emitting part is arranged not to emit the light to the portion of the drawing region when the droplet discharge head is disposed at a position over the portion, and to emit the light to the portion when the droplet discharge head has moved away from the position.

  • Patent number: 7755719
    Abstract: A color filter has a light-transmissive substrate, a reflecting layer formed on the back substrate and provided with openings, boundary layers and formed on the reflecting layer, and a plurality of coloring layers enclosed by the boundary layers. A transparent coat layer is provided between the reflecting layer and the boundary layers. A step is formed between the openings and the transparent coat layer. The coloring layers are formed by applying the droplets of colored fluid to the openings first, and then to the transparent coat layer. The difference in color saturation of the color filter in a reflective display mode and a transmissive display mode is reduced. Also, a liquid material is appropriately applied to the color filter, to enhance color balance.

  • Patent number: 7504766
    Abstract: To enhance the brightness and contrast of a display, and to enhance the visibility of a color filter, a color filter includes a substrate that transmits light, a reflective layer that is formed on the substrate and includes openings, boundary layers formed on parts of the reflective layer, and a plurality of colored layers that are surrounded by the boundary layers. As the boundary layers, boundary layers that transmit light are formed between colored layers of the same color and boundary layers that do not transmit light are formed between colored layers of different colors.

  • Patent number: 7430029
    Abstract: A color filter substrate includes first and second layers having openings, a filter layer located in the openings, a reflecting component, and a transmitting component. The reflecting component is provided at least partially on a second side of the filter layer such that first light rays that are incident on the filter layer from a first side are reflected to the first side, where the first side is an opposite side of the second side. The transmitting component is provided at least partially on the second side of the filter layer, such that second light rays that are incident on the filter layer from the second side are emitted to the first side. The present invention provides a color filter substrate, a liquid crystal display device, and an electronic device having a structure that allows good coating with a liquid material.

  • Patent number: 7298435
    Abstract: A color filter 40 has a light-transmissive substrate 2, a reflecting layer 3 formed on the back substrate 2 and provided with openings 4, boundary layers 5 and 21 formed on the reflecting layer 3, and a plurality of coloring layers 6 enclosed by the boundary layers 5 and 21. A transparent coat layer 25 is provided between the reflecting layer 3 and the boundary layers 5 and 21. A step is formed between the openings 4 and the transparent coat layer 25. The coloring layers 6 are formed by applying the droplets 150 of colored fluid to the openings 4 first, and then to the transparent coat layer 25. The difference in color saturation of the color filter 40 in a reflective display mode and a transmissive display mode is reduced. Also, a liquid material is appropriately applied to the color filter 40, to enhance color balance.
