Patent number: 7029727Abstract: A thin film transistor (TFT) is formed on an insulating substrate, and a photosensitive resin film as an interlayer insulating film is formed so as to cover the TFT. Contact holes are formed in the photosensitive resin, and smooth concave and convex portions are provided on an upper surface of the resin. A film including molybdenum nitride (MoN) and a reflective pixel electrode film are successively laminated on the photosensitive resin. The nitrogen content in the MoN film may be between 5 atomic % and 30 atomic % inclusive.Type: GrantFiled: October 26, 2000Date of Patent: April 18, 2006Assignee: Sharp Kabushiki KaishaInventors: Masafumi Kokura, Yoshiharu Kataoka, Takayuki Shimada

Patent number: 6899957Abstract: An antireflection film is formed of an organic film, and a hard-coating layer, a high refractive index layer and a low refractive index layer laminated in this order on the organic film. The high refractive index layer is formed of metal oxide particles of ITO with electrical conductivity and TiO2 with high refractive index, and synthetic resin. A volume percentage of the TiO2 particles to a total volume of the TiO2 and ITO particles in the high refractive index layer is 1 to 60%, and a volume percentage of the metal oxide particles to a total volume of the metal oxide particles and the synthetic resin is 20% or more.Type: GrantFiled: November 16, 2001Date of Patent: May 31, 2005Assignee: Bridgestone CorporationInventors: Mitsuhiro Nishida, Shingo Ohno, Masato Yoshikawa, Nobuko Kato

Patent number: 6884495Abstract: An antireflection film is formed of an organic film, a hard hard coating layer on the organic film, a first layer coated on the hard coating layer, and a second layer having an index of refraction lower than that of the first layer and coated on the first layer. The first layer is formed of a synthetic resin having pores therein and metallic oxide particles contained in the synthetic resin. The metallic oxide is at least on selected from the group consisting of ZrO1, TiO2, NbO, ITO, ATO, SbO2, In2O3, SnO2 and ZnO. The synthetic resin is ultraviolet ray curable resin or electron beam curable resin. The second layer partly enters the pores of the first layer to firmly bond to the first layer through the pores.Type: GrantFiled: April 19, 2001Date of Patent: April 26, 2005Assignee: Bridgestone CorporationInventors: Mitsuhiro Nishida, Shingo Ohno, Masato Yoshikawa, Nobuko Kato

Publication number: 20040247906Abstract: An optical thin film stack for a dark aperture is deposited using thermal ion-assisted deposition (“IAD”). The IAD provides an energetic deposition of chromium and chromium oxide that results in a dark mirror optical thin film stack with superior etch properties. Edge definition is improved, and the edge profile is controllable by the selection of IAD parameters. An in situ IAD cleaning process can be used to clean the substrate sufficiently so that an intermediate adhesion layer of chromium is not required.Type: ApplicationFiled: May 24, 2002Publication date: December 9, 2004Applicant: Optical Coating Laboratory, Inc., a JDS Uniphase CompanyInventor: Paul J.
