  • Publication number: 20230394867
    Abstract: According to an aspect, a detection device includes: a substrate having a detection region; a plurality of photodiodes provided in the detection region; a first light-transmitting resin layer provided so as to cover the photodiodes; a light-blocking layer provided on the upper side of the first light-transmitting resin layer and provided with openings in regions overlapping the respective photodiodes; a second light-transmitting resin layer provided so as to cover the light-blocking layer; and a plurality of lenses provided on the upper side of the second light-transmitting resin layer so as to overlap the respective photodiodes. The second light-transmitting resin layer is provided so as to cover an end on a peripheral side of the light-blocking layer on a peripheral side of the substrate.

  • Patent number: 6806640
    Abstract: Provided is an organic electroluminescence device which operates at a low voltage, has a uniform light emission surface, and can display high-quality images. In an organic electroluminescence device, an anode, a hole transport layer made of an organic compound, a light emitting layer made of an organic compound, and a cathode are stacked in the order named, and an electron injection layer containing a lanthanoid oxide is formed between the light emitting layer and cathode. The anode and/or cathode is made of a transparent conductive material. In another organic electroluminescence device, an anode, a hole transport layer made of an organic compound, a light emitting layer made of an organic compound, and a cathode are stacked in the order named, and an electron injection layer formed by mixing a lanthanoid metal oxide and organic compound is formed between the light emitting layer and cathode.

  • Patent number: 6570180
    Abstract: The object of the present invention is to provide an organic light emitting device which can be operated at a low voltage, and when such elements are used in a display panel, a light-emitting surface which can emit light uniformly over an entire display panel can be obtained when the conditions are maintained the same. The organic light-emitting device of the present invention includes a substrate having a light transmitting property in a visible range, a first electrode having a light transmitting property in a visible range, and formed on the substrate, a layer formed on the first electrode, and configured to emit light by recombination of excitons each made of a pair of a positive hole and electron injected thereto, and a second electrode containing erbium and formed on the layer.
