  • Publication number: 20170141170
    Abstract: A display device includes plurality of light-emitting elements aligned on a TFT substrate in a formation of a matrix. The plurality of light-emitting elements each have a flat surface portion and including a light-emitting layer, an anode, and a cathode, an insulating layer formed on the TFT substrate and under the light emitting element, and a tilted metal surface provided on a peripheral area surrounding the flat surface portion of the light-emitting element and having a tilt angle with respect to the flat surface portion of the light-emitting element. The tilted metal surface is provided on a surface of a slope of a bank that is provided on the insulation layer, and a width of a cross-section of the bank becomes smaller as the cross section comes farther away from a surface of the TFT substrate. A counter substrate is placed on the TFT substrate.

  • Patent number: 9614178
    Abstract: In an electronic component including two substrates at least one of which is transparent, an organic member arranged between these substrates, and a bonding portion located onto respective outer circumferential portions of the two substrates, this bonding portion includes a low-melting glass and filler particles. The low-melting glass includes vanadium oxide. The filler particles include a low thermally-expandable material, and an oxide containing a bivalent transition metal as a constituent element. The oxide is dispersed in the low thermally-expandable material, and the low thermally-expandable material has a thermal expansion coefficient of 5×10?7/° C. or less in a temperature range from 30 to 250° C. This invention makes it possible to heat the filler particles by irradiation with a laser to give the electronic component which is a component having a highly reliable bonding portion.
