  • Patent number: 10328710
    Abstract: A recording apparatus includes a recording head, an ink supply section, a carriage, and a detection unit. The ink supply section supplies ink to the recording head. The carriage reciprocates in predetermined directions and is provided with the recording head and includes a passage junction to be connected to or disconnected from an ink passage formed between the ink supply section and the recording head. The detection unit converts a result of detecting a detection target into an electrical signal. One of the detection target and the detection unit is mounted in the carriage. The carriage has an ink guiding mechanism that guides the ink from a region positioned below the passage junction in a vertical direction to the detection target or an installation part for the detection unit.

  • Patent number: 7630115
    Abstract: A substrate for an electrooptic device comprising a light-transmissive base member, a reflection layer formed on the base member so as to include each reflection portion and a corresponding transmission portion having a transmission factor higher than that of the reflection portion, a light transmission layer formed over the base member so as to coincide with the reflection layer and to include each hollow at a position that coincides with the transmission portion in plane, and an orientation film formed over the base member so as to coincide with the light transmission layer and to define a concavity while entering the corresponding hollow. The thickness “b” of a liquid crystal layer corresponding to the concavity is greater than the thickness “a” of the liquid crystal layer at the other positions thereof.

  • Patent number: 7612846
    Abstract: A reflective layer 212 having an aperture 212a for each pixel is formed on a first substrate 211, and a colored layer 214 for constituting a color filter is formed thereon. A surface protection layer 215 is formed on the colored layer 214, and a transparent electrode 216 is formed further thereon. The colored layer 214 is constituted so as to cover the aperture 212a in a two-dimensional direction, but overlaps only a part of a reflection surface in the pixel in a two-dimensional direction.

  • Patent number: 7486353
    Abstract: Each color filter 22 includes a deep-color portion 221 being superimposed on a translucent portion 211 of a reflection layer 21 and a light-color portion 222 having an optical density lower than that of the deep-color portion 221. A light-shielding layer 23 for shielding the gaps between individual subpixels 7 from light is a laminate composed of at least a deep-color portion 221B of a blue color filter 22B, a deep-color portion 221R of a red color filter 22R, and a deep-color portion 221G of a green color filter 22G.

  • Patent number: 7336327
    Abstract: A transflective color filter substrate is provided. The transflective color filter substrate comprises a transmissive color filter portion and a reflective color filter portion in one dot region. An area of the color filter colored portion is set to be less than the area of one dot region in the transflective color filter substrate, and an uncolored reflection region, which is capable of reflecting an uncolored light of high brightness without being influenced by the color filter, is formed by a partition layer. Since the pigment density of the coloring layer is set such that the transmitted light has the optimum chroma in the transmissive display mode, it is possible to obtain a displayed image having sufficient chroma in the transmissive display mode.
