  • Patent number: 8894836
    Abstract: A highly reliable electronic device that prevents entry of a plating solution via an external electrode and entry of moisture of external environment inside thereof, and generates no soldering defects or solder popping defects which are caused by precipitation of a glass component on a surface of the external electrode. The electrode structure of the electronic device is formed of Cu-baked electrode layers primarily composed of Cu, Cu plating layers formed on the Cu-baked electrode layers and which are processed by a recrystallization treatment, and upper-side plating layers formed on the Cu plating layers. After the Cu plating layers are formed, a heat treatment is performed at a temperature in the range of a temperature at which the Cu plating layers are recrystallized to a temperature at which glass contained in a conductive paste is not softened, so that the Cu plating layers are recrystallized.

  • Patent number: 8211599
    Abstract: A green pigment for a color filter including a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by predetermined equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry. Moreover, using the above-mentioned green pigment, it provides a photosensitive color composition capable of forming a color filter having a wide color reproduction range and a high transmittance. Furthermore, it provides a color filter having a wide color reproduction range and a high transmittance with a green pixel formed using the above mentioned photosensitive color composition, and a liquid crystal panel using the color filter.

  • Patent number: 6826001
    Abstract: The present invention provides a color filter which is more durable than a dye-type color filter and also has green pixel portions which exhibit a bright green color having a strong yellowish tinge when used in a liquid crystal display device using a three-band lamp having a main emission line of green light of about 545 nm as a light source, thus enabling the liquid crystal display device to display bright images even when using a backlighting light source having a low intensity. This color filter comprises green pixel portions which (1) contain a halogenated metal phthalocyanine dye wherein 8 to 16 halogen atoms are bonded to benzene rings in one phthalocyanine molecule, and (2) exhibit maximum transmittance at a wavelength within a range from 520 nm to 590 nm with respect to the transmission spectra of the entire range of visible light.
