The invention relates to a control device for controlling the color of light emitted from a light source. The liquid crystal display device has signal lines for driving individual pixels and a driver circuit connected to the signal lines, on a liquid-crystal-side surface of either one of substrates disposed to oppose each other with a liquid crystal interposed therebetween. This results in the provision of a high-quality vacuum heat insulation material with excellent long-term insulation performance by using a covering material excellent in gas barrier properties and pinhole resistance to the piercing of minute foreign bodies. Rotation of the shaft effects rotation of the pinion gear. The components may include a transport module, a fluidics module, and an analysis module, among others. For a differential digital phase mixer, the propagation delay is reduced in the rising and falling edges of the output signal.
