  • Patent number: 8563200
    Abstract: A manufacturing method of a photomask by which a resist pattern corresponding to a pattern with designed values can be formed, a method for optical proximity correction, and a manufacturing method of a semiconductor device are provided. Proximity design features that are close to each other and estimated to violate a mask rule check are extracted. In the proximity design features, correction prohibited regions where optical proximity correction is not carried out are set based on the distance between the features obtained from the extracted proximity design features and the resolution of an exposure device. Optical proximity correction is carried out on the proximity design features with the correction prohibited regions excluded to obtain corrected proximity patterns. A predetermined mask material is patterned by carrying out electron beam lithography based on the corrected proximity pattern data.

  • Publication number: 20130235097
    Abstract: A stereoscopic display device includes: a parallax barrier in which light transmission parts that transmit light and light shielding parts that block light are formed alternately, and a display panel that displays a stereoscopic image. A plurality of pixels for displaying the stereoscopic image are formed on the display panel. Each pixel includes a plurality of color forming subpixels that contribute to the color formation of the stereoscopic image, and a contrasting subpixel that contributes to the contrast of the stereoscopic image. In each pixel, the contrasting subpixel is positioned at both ends of the pixel in a direction in which the light transmission parts and the light shielding parts are arranged alternately. In each pixel that overlaps the light shielding part when the display panel is viewed from front, the contrasting subpixel is positioned at both ends of the light shielding part.

  • Patent number: 8330674
    Abstract: A multiplex image display device prevents onscreen input buttons from appearing at the same positions. A “command area” refers to an area of the display screen where the user can enter a command for manipulating one of images being simultaneously displayed on the single display section for individual viewing from different directions. In the multiplex image display device, the positioning control section controls the positioning of the command areas so that a command area for one of the images being simultaneously displayed on the display section is displayed at a different (i.e., non-overlapping) position on the display section from a command area for another one of such images.
