摘要： A light emitting apparatus (10) includes a substrate (100), an insulating layer (160), a light emitting element (102), a coating film (140), and a structure (150). The insulating layer (160) is formed over one surface of the substrate (100), and includes an opening (162). The light emitting element (102) is formed in the opening (162). The coating film (140) is formed over the one surface of the substrate (100), and covers a portion of the light emitting element (102), the insulating layer (160), and the one surface of the substrate (100). The coating film (140) does not cover another portion of the substrate (100) (for example, a portion of an end portion: hereinafter, referred to as a first portion). The structure (150) is located between the first portion of the substrate (100) and the insulating layer (160). The coating film (140) also covers the insulating layer (160).

摘要： When visible light (light having wavelength of 380 nm or more and 780 nm or less) is transmitted through a first light transmitting region (TR1) (a first light emitting portion (160a)), a second light transmitting region (TR2) (a second light emitting portion (160b)) and a third light transmitting region (TR3) (a first light transmitting portion (162)), more specifically, when light from a D65 light source is transmitted through the first light transmitting region (TR1), the second light transmitting region (TR2) and the third light transmitting region (TR3), both of a color difference between the first light transmitting region (TR1) and the third light transmitting region (TR3) and a color difference between the second light transmitting region (TR2) and the third light transmitting region (TR3) are both, for example, 0.4 or more and 6.5 or less in CIELAB. This reduces conspicuousness of both of the first light transmitting region (TR1) and the second light transmitting region (TR2). Furthermore, it is possible to identify the first light transmitting region (TR1), the second light transmitting region (TR2), and the third light transmitting region (TR3).

摘要： Provided is a sound generation device wherein noise can be reduced in accordance with a predetermined frequency band. An elastic member (8) is provided to obtain a sound pressure characteristic having a sub-peak at a predetermined frequency on the lower side than a lowest resonance frequency, and a phase characteristic such that a change rate of phase difference is lowered around the predetermined frequency. When the phase characteristic is calculated by simulation or actually measured in advance and an input signal is controlled such that the generated sound has an opposite phase to the noise, the generated sound can be made less prone to deviate from the opposite phase to the noise even if a time difference is caused between noise sound collection and sound generation at around the predetermined frequency, with the result that the noise can be effectively reduced. In addition, restrictions regarding the equivalent mass and resonance frequency of a diaphragm (3) can be reduced, the flexibility of design can be improved, and the noise can be reduced in accordance with the predetermined frequency band.

摘要： A substrate (100) is a light-transmitting substrate. A light-transmitting first electrode (110) is formed over the substrate (100). An insulating layer (150) is formed over the substrate (100) and the first electrode (110) and includes an opening (152) overlapping the first electrode (110). An organic layer (120) is located within at least the opening (152). A light-transmitting second electrode (130) is formed over the organic layer (120). An intermediate layer (200) is formed in at least a portion of a region of a lateral side of the first electrode (110) overlapping the first electrode (110). A refractive index of the intermediate layer (200) is between a refractive index of the substrate (100) and a refractive index of the first electrode (110).

摘要： A speaker unit emits a sound towards a box-like space formed by a vehicle. The speaker unit is accommodated in an enclosure. At least one of the enclosure and the speaker unit is provided with a tubular member and/or a vibration member configured to generate a resonance sound of a frequency different from a lowest resonance frequency of the speaker unit. At least a part of the enclosure also serves as a body of the vehicle.

摘要： A light-emitting device (10) is, for example, a segment type display device, a display, or a lighting device, and includes a light-emitting portion (140), a light-transmitting portion (142), and an insulating film (150). The light-emitting portion (140) has a first electrode (110), an organic layer (120), and a second electrode (130). The light-transmitting portion (142) has the first electrode (110), the second electrode (130), and a first layer. The first layer is located between the first electrode (110) and the second electrode (130) . In an example illustrated in the figure, the first layer is at least a part of the organic layer (120). The insulating film (150) defines the light-emitting portion (140) and is located in the light-transmitting portion (142).
