摘要:
An organic electroluminescent apparatus 1 including: a first emitting device 10 having a first organic emitting layer 14 between a first lower electrode 12 and a first upper electrode 16, and a second emitting device 20 having a second organic emitting layer 24 between a second lower electrode 22 and a second upper electrode 26. The second lower electrode 22 is electrically connected to the first upper electrode 16 or is made of the same material as the first upper electrode 16. The two devices 10 and 20 are placed on a common surface, yet the two devices 10 and 20 exhibit different emission colors.
摘要:
A color-changing material composition which comprises a binder resin comprising a copolymer of a methacrylic ester and methacrylic acid having a specific structure (Component A), at least one fluorescent coloring matter (Component B) and a monomer and/or oligomer having a photopolymerizable ethylenically unsaturated group (Component C) and color-changing membranes formed by curing the color-changing material composition are provided. Degradation of the color-changing membrane due to continuous lighting of a light source can be decreased, the increase in viscosity of the composition can be suppressed, and deterioration of rhodamine can be prevented by using the color-changing material composition and the color-changing membrane using the composition.
