Abstract
A liquid crystal display device of the present invention includes: a liquid crystal layer that is held between first and second substrates; an upper polarization plate that is disposed on an outer side of the first substrate; and a protection plate that is fixed to and disposed on an outer side of the upper polarization plate, wherein the upper polarization plate has a structure where an outer peripheral portion of the upper polarization plate is not fixed to the protection plate.
Claims11
A liquid crystal display device comprising:
- a liquid crystal module equipped with a tabular first substrate, a tabular second substrate that has a smaller area than that of the first substrate, a liquid crystal layer that is held between the first and second substrates, a lower polarization plate that is disposed on an outer side of the first substrate and an upper polarization plate that is disposed on an outer side of the second substrate;
- and
- a transparent protection plate that has a larger area than that of the second substrate and is fixedly attached to and disposed on an outer side of the upper polarization plate;
- wherein the upper polarization plate has a structure where an outer peripheral portion of the upper polarization plate is not fixed to the protection plate or the second substrate that faces this outer peripheral portion;
- wherein an inner surface of the protection plate that faces the outer peripheral portion of the upper polarization plate recedes toward an outer surface of the protection plate and faces, without contacting, the upper polarization plate;
- and
- wherein the inner surface of the protection plate that faces the outer peripheral portion of the upper polarization plate has a tapered shape.
