  • INPUT APPARATUS, DISPLAY APPARATUS HAVING AN INPUT FUNCTION, INPUT METHOD, AND METHOD OF CONTROLLING A DISPLAY APPARATUS HAVING AN INPUT FUNCTION
    Publication number: 20110084985
    Abstract: An input apparatus having an input surface touched by an object body at input time, the input apparatus includes: when a contact area of the object body on the input surface increases, an increase-direction detection section generating increase-direction information corresponding to the increase direction of the contact area; and when the contact area of the object body on the input surface is moved, a movement-direction detection section generating movement-direction information corresponding to the movement direction of the contact area.

  • Transflective liquid crystal device having a wire serpentinely bypassing a light-shielding layer in an interpixel region
    Patent number: 7839471
    Abstract: A liquid crystal device has a plurality of pixels arranged. The liquid crystal device includes a first substrate, a second substrate opposing the first substrate, liquid crystal provided between the first substrate and the second substrate, wires formed on the first substrate, and a reflective layer formed on the first substrate. Each pixel has a reflective display region formed by the reflective layer and a transparent display region without the reflective layer, and each wire is routed between two pixels in the transparent display region and in the reflective display region.

  • Manufacturing method of electro-optical apparatus substrate, manufacturing method of electro-optical apparatus, electro-optical apparatus substrate, electro-optical apparatus, and electronic instrument
    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.
