Abstract:
A light-emitting apparatus includes an excitation light source that emits first light; a light-emitting device on an optical path of the first light, the light-emitting device emitting second light having a wavelength in air; and a first converging lens on an optical path of the second light. The light-emitting device comprises: a photoluminescent layer that emits the second light by being excited by the first light; and a light-transmissive layer on the photoluminescent layer. At least one of the photoluminescent layer and the light-transmissive layer has a surface structure comprising projections or recesses arranged perpendicular to a thickness direction of the photoluminescent layer. At least one of the photoluminescent layer and the light-transmissive layer has a light emitting surface perpendicular to the thickness direction, the second light emitted from the light emitting surface. The surface structure limits the directional angle of the second light emittied from the light emitting surface.
Abstract:
A aspect of the present disclosure provides a base material with a transparent conductive film on or above the base material. The transparent conductive film includes a conductive layer containing metal wires, and a protective layer being located on a side of the conductive layer and containing a resin and a particle, the side not opposing to the base material. The particle is soluble in an acidic etching solution, and the resin is resistant to the acidic etching solution.
Abstract:
A base material with a transparent conductive film on or above the base material is provided. The transparent conductive film includes a conductive layer; and a protective layer being located on a side of the conductive layer and containing a first resin, the side not opposing to the base material. The transparent conductive film includes a conductive portion and a non-conductive portion in a plan view. The conductive layer contains no metal wires in the conductive portion or contains less metal wires per unit area in the non-conductive portion than the conductive layer contains the metal wires per unit area in the conductive portion. The protective layer contains a particle in the conductive portion, and includes an aperture penetrating the first resin in a thickness direction in the non-conductive portion. The particle is soluble in an acidic etching solution, and the first resin is resistant to the acidic etching solution.
