Abstract: A display device includes a backlight, a display element, a plate for holding at least a portion of an emission surface, from which an image light is emitted, provided on the display element, and a heat dissipation portion that dissipates heat generated from the display element. The display element is connected to the heat dissipation portion via the plate.

Abstract: A process for selectively separating water vapor from a multiple component gaseous mixture is provided. The process comprises passing a multicomponent gaseous mixture including water vapor along and in contact with a membrane which is selectively permeable to water vapor and wherein the water vapor permeation rate Q.sub.H.sbsb.2.sub.O is greater than 30 Nm.sup.3 /m.sup.2 .multidot.hr.multidot.atm at 25.degree. C. and the ratio of Q.sub.H.sbsb.2.sub.O to the permeation rate Q.sub.G of the gas to be separated from the water vapor, i.e., Q.sub.H.sbsb.2.sub.O Q.sub.G, is greater than 10,000. The membrane preferably has a thickness of about 0.1 microns to about 50 microns.
