A liquid crystal display includes: a transmissive liquid crystal display device having a display region made up of pixels arrayed in a matrix fashion. The loudspeaker system emits sound by driving a diaphragm panel by an electromechanical acoustic transducer. NO2 in the sample gas is converted to NO by passing the sample gas through a catalytic NO2 converter. A portion of the dielectric layer at the periphery of the polysilicon layer is etched away, leaving a gap between the polysilicon patterned layer and the underlying substrate contact region. As mined, Yenomite contains very low levels of undesired Na+ ions. In particular, the invention is illustrated by a recombinant chimeric protein between human interleukin-2 and Bax.
