Description

  The present invention relates to an optical device, an electronic device, a sealing composition used for sealing for protecting the optoelectronic device from the external environment, a sealing agent, and a sealing method using the sealing agent. The sealing agent of the present invention includes semiconductor electronic components such as diodes, transistors, and ICs, liquid crystal panels, plasma display panels, display elements such as electroluminescence (hereinafter, EL) elements, and high-density recording media such as magneto-optical disks. It can be used for sealing solar cells, optical waveguides and the like.

  Since optical devices, electronic devices, and optoelectronic devices are greatly affected by changes in ambient temperature and humidity, it is well known that they are sealed with liquid resin and used in a state protected from the external environment. . In recent years, flip chip mounting, in which a bare chip is directly connected to a printed circuit board, has attracted attention as a semiconductor chip mounting method. This is to melt-connect the metal bump electrodes on the element forming surface of the bare chip to the electrode pads formed on the printed circuit board. The underfill agent is used to reduce stress between the circuit board and the chip. (Patent Documents 1 and 2).

  The liquid crystal display has a structure in which liquid crystal is sealed between two parallel liquid crystal substrates, and a transparent electrode is laminated on the liquid crystal substrate, and a sealing agent as a sealing material for sealing the liquid crystal Is used. Conventionally, a thermosetting epoxy resin has been used as the sealing material. However, such a thermosetting epoxy resin needs to be heated at a high temperature of 150 to 180 ° C. for about 2 hours, and there is a problem that productivity does not increase.

  In addition to such a thermosetting method, an ultraviolet curable encapsulant composition has been studied for the purpose of improving productivity and sealing a heat-sensitive substrate (Patent Documents 3 and 4). ), The irradiation energy required for curing is large, and further improvement in productivity is desired.

  On the other hand, in an EL display, a sealing agent is used as a sealing material for bonding (sealing) a glass substrate constituting an element and an airtight container. The EL element includes an inorganic EL element and an organic EL element. The organic EL element is superior to the inorganic EL element in terms of high luminance, high efficiency, high-speed response, and multicolorization, but has low heat resistance and a heat resistance temperature of about 80 to 100 ° C. For this reason, the seal of the organic EL display has a problem that it cannot be sufficiently heated and cured even if a thermosetting epoxy resin is used as a sealant. In recent years, attempts have been made to develop a photo-curing sealing material that can be cured at a low temperature and a high speed. However, when irradiating light with a wavelength of less than 350 nm, the organic dye of the organic EL element deteriorates and the emission intensity becomes insufficient, and with irradiation with light with a wavelength of 350 nm or more, Curability is still insufficient (Patent Document 5).

  Furthermore, many proposals have been made to seal the light emitting diodes with resin. Among these, white LEDs are attracting attention as illumination light sources that can realize significant energy savings. Therefore, it is important how to efficiently extract the light emitted from the light-emitting diode element (LED chip), and the LED chip sealant is required to be non-colored and highly transparent (Patent Literature). 6).
