Abstract
The present invention is to provide a novel transparent type liquid crystal display having a high contrast and transmittance that does not depend on an open area ratio without reducing a response speed. More specifically, the transparent type liquid crystal display of the present invention comprises at least a pair of first and second substrates,and,and a liquid crystal layer,interposed between the first and second substrates,and,. A plurality of first light transmission portions,are formed on the first substrate,, and a plurality of second light transmission portions,are formed on the second substrate,. First reflective components,and second reflective components,are disposed on the respective main surfaces,A and,A of the first and second substrates,and,so that an external light entering into a transparent type liquid crystal display,through a plurality of first light transmission portions,is reflected by the first and second reflective components,and,and thereby passes through the liquid crystal layer,a plurality of times and then the external light exits through the second light transmission portions
