Reflection type liquid crystal display device in which oblique moiré fringe is not easily viewed and which is superior in display quality

A reflection type liquid crystal display device comprising:

• an upper and a lower substrate,
• a liquid crystal layer provided between the upper and lower substrates, the upper and lower substrates having an inner side more proximate to the liquid crystal layer and an outer side more distal to the liquid crystal layer;
• a plurality of transparent electrodes formed on at least one of the inner side of the upper and lower substrates, the plurality of transparent electrodes extending in a first predetermined direction;
• color filters provided on one of the inner sides of the upper and lower substrates and having a plurality of colored pixels aligned in a second predetermined direction;
• and
• a reflection member disposed on one of the inner and outer sides of the lower substrate, the reflection member having a plurality of recesses arranged in a third predetermined direction;
• wherein the third and second predetermined directions deviate about 2.5 to about 40 degrees from each other when extending along planes substantially parallel with each other.

A reflection type liquid crystal display device comprising:

• a pair of substrates;
• a liquid crystal layer disposed between the pair of substrates, each substrate having an inner side more proximate to the liquid crystal layer and an outer side more distal to the liquid crystal layer;
• a plurality of transparent electrodes formed in parallel directions at predetermined intervals on inner sides of each of the pair of substrates, the plurality of transparent electrodes formed in a first parallel direction on one substrate of the pair of substrates and the plurality of transparent electrodes formed in a second parallel direction on the other substrate of the pair of substrates, the first parallel direction orthogonal to the second parallel direction;
