  • Patent number: 7224505
    Abstract: A manufacturing process of an electro-optical apparatus substrate is provided wherein a substrate is coated with a photosensitive resin. A first exposure process is executed with a first reticle to form an uneven portion on the substrate. Subsequently, a second exposure process is executed with a second reticle to remove all the photosensitive resin on portions other than the uneven portion. After the second exposure process, the substrate is developed so as to form an underlying film having an uneven portion.

  • Publication number: 20070064184
    Abstract: A liquid crystal device includes a pair of substrates, liquid crystal sandwiched between the pair of substrates, and a plurality of sub-pixels. Each sub-pixel has a transmissive display region and a reflective display region. One of the substrates has a color filter and a transparent insulating film disposed on the color filter. The transparent insulating film has a thin-walled portion provided in the transmissive display region and a region along a boundary between the adjacent sub-pixels. At least a portion of a region in which the thin-walled portion of the transparent insulating film is not provided overlaps the reflective display region. The layer thickness of the liquid crystal in the reflective display region is smaller than the layer thickness of the liquid crystal in the transmissive display region in consideration of the thin-walled portion.

  • Publication number: 20070008461
    Abstract: An electro-optical device includes: a plurality of display pixels each of which has two Red sub-pixels, two Green sub-pixels, one Blue sub-pixel, and one transparent sub-pixel; and a colored layer which is partially formed on the Red, Green, and Blue sub-pixels. In the electro-optical device, uncolored portions are formed in parts of the Red and Green sub-pixels where the colored layer is not formed.
