| titleOfInvention | Backlight device for liquid crystal display |
| abstract | PROBLEM TO BE SOLVED: To achieve λ / 4 over a wide band of visible light. Provided is a backlight device for a liquid crystal display which has a / 4 wavelength plate, improves the efficiency of using the amount of light from a light source, and is excellent in mass productivity and performance stability. A light reflecting electrode, a light emitting layer, a transparent electrode, and a quarter A backlight device for a liquid crystal display in which a wave plate and a circularly polarizing plate having a linear polarizing film are arranged in this order, wherein the quarter-wave plate has a single layer and a wavelength λ. Is less than Re (450) < A backlight device for a liquid crystal display, which has a characteristic of Re (550) <Re (650). 1 The / 4 wavelength plate is formed of a mixed material containing a material having a positive intrinsic birefringence value and a negative material, or a chain portion having a positive uniaxial property and a chain portion having a negative uniaxial property. An embodiment comprising a composition containing a copolymer (preferably, a graft copolymer) is preferred. |
