Abstract
A transmission-type display device including: a first transparent substrate having pixel electrodes and switching elements formed thereon, each of the pixel electrodes being connected to the respective switching element; a second transparent substrate having a counter electrode formed thereon and being positioned opposite to the first transparent substrate in such a manner as to leave a gap therebetween; a liquid crystal layer held in the gap between the first transparent substrate and the second transparent substrate; and a heat-dissipating glass plate of a thermal conductivity of 1 W/m.multidot.K or more and a thickness of 1 mm or more arranged at the outer surface of at least the first transparent substrate constructed in such a manner that picture quality does not deteriorate even if dust becomes attached to the liquid crystal panel or lens. Instead, the heat-dissipating glass plate can be bonded to the outer surface of the first transparent substrate in such a manner as to leave a gap of width of 2 mm or less between the heat-dissipating glass plate and the first transparent substrate.
