Patent number: 8206618Abstract: A color filter ink set is adapted to be used to manufacture a color filter by an inkjet method. The color filter ink set includes a plurality of inks with each of the inks including a colorant and a liquid medium that disperses and/or dissolves the colorant. The inks include a green ink having C. I. Pigment Green 58 and a substance represented by a prescribed chemical formula. A viscosity at 25° C. of the liquid medium of the green ink is lower than a viscosity at 25° C. of the liquid medium of the ink other than the green ink. A difference (?max??min) between a viscosity (?max (mPa·s)) of the ink having the highest viscosity among the inks at 25° C. and a viscosity (?min (mPa·s)) of the ink having the lowest viscosity among the inks at 25° C. is 1.0 mPa·s or less.Type: GrantFiled: December 24, 2008Date of Patent: June 26, 2012Assignee: Seiko Epson CorporationInventors: Hidekazu Moriyama, Masaya Shibatani, Hiroshi Kiguchi, Hiroshi Takiguchi

Patent number: 8192579Abstract: After a gate line (11), a TFT (1), and a data line (30) are formed, a riblike protective insulation layer (32) which coats the data line is formed on a substrate (10) serving as the element substrate of an active matrix type color liquid crystal display device or an organic EL display device. A color filter layer (42) on a transfer film (40) is press-bonded on this substrate (10) with a roller (46) moving in the extensional direction (columnar direction) of the protecting insulation layer (32). The advancement of the transfer of a color filter in the columnar direction makes it possible to bring the substrate and the color filter in contact without gaps while expelling the gas out of a pixel space in the advancement direction. During the step of forming a color filter, the protecting insulation layer (32) protects the data line (30) from the treatment liquid etc. An organic light emitting element layer is arranged in the pixel space to form an organic EL display device.Type: GrantFiled: March 10, 2008Date of Patent: June 5, 2012Assignee: Sanyo Electric Co., Ltd.Inventors: Hideki Matsuoka, Kazuyuki Maeda
