Patent number: 9389357Abstract: A backlight device wherein LEDs which are arranged side by side at a first arrangement interval (P1) are provided to each LED unit. The LED units are mounted to a flexible board at a second arrangement interval. A light guide plate is disposed in such a manner that an end surface thereof is spaced from the LEDs by a distance (H). The light guide plate is disposed so as to satisfy the following relationship: first arrangement interval (P1)<distance (H)<second arrangement interval (P2). Specifically, the LEDs are arranged side by side in such a manner that the first arrangement interval (P1) is not less than 0.1 mm but not greater than 3 mm and the second arrangement interval (P2) is not less than 5 mm but not greater than 15 mm. The light guide plate is disposed in such a manner that the distance (H) is not less than 1 mm but not greater than 7 mm.Type: GrantFiled: July 10, 2014Date of Patent: July 12, 2016Assignee: JVC KENWOOD CorporationInventors: Naoto Hirohata, Yasuhiro Ueki, Nobuyoshi Yamagishi, Takuya Kakinuma, Mikio Okumura

Publication number: 20070046880Abstract: A liquid crystal display apparatus includes a driver substrate having a pixel area with pixel electrodes and drive circuits each driving the corresponding pixel electrode arranged in a matrix in the pixel area and a transparent substrate having an opposing electrode. The driver substrate and the transparent substrate face each other with a liquid crystal filled between the pixel electrodes and the opposing electrode. A dielectric material is provided in a gap between each pair of two adjacent pixel electrodes, with 0.2 ? or lower (? being a wavelength of reading light to be used) in phase difference of a step created on the dielectric material provided in the gap with respect to each pixel electrode. A first dielectric film and a second dielectric film are laminated in order in the pixel area. The second dielectric film exhibits a higher refractive index than the first dielectric film.Type: ApplicationFiled: August 16, 2006Publication date: March 1, 2007Applicant: Victor Company of Japan, Ltd. a corporation of JapanInventors: Masanobu Shigeta, Tetsuhiro Yamazaki, Hiroyuki Natsuhori, Masanobu Yoshida, Takuya Kakinuma
