ABSTRACT:
A reflection-type liquid crystal display device includes a first substrate, a second substrate facing the first substrate and carrying projections and depressions, a reflective electrode on the second substrate so as to cover the projections and depressions and in electrical contact with a switching device provided on the second substrate via a contact hole, and a negative liquid crystal layer between the first and second substrates, wherein the contact hole is disposed centrally to the reflection electrode and a structure controlling alignment of liquid crystal molecules in the liquid crystal layer is disposed so as to overlap the contact hole viewed in a direction perpendicular to the second substrate.
