The liquid crystal display device and a partial transmission type liquid crystal display device

2002 
The present invention includes a first substrate, a second substrate, a liquid crystal layer sandwiched between the first substrate and the second substrate, a driving unit, reflectance - applied voltage characteristic a normally closed type, the transmittance - in the liquid crystal display device applied voltage characteristic is normally closed-type, the first substrate has a common electrode, an upper polarizing plate and the upper phase plate on an upper surface, a second the substrate has a reflective electrode and a transparent electrode connected to the active element, the lower polarizing plate and the lower phase plate on the lower surface, the liquid crystal layer has a twist angle of less 65 degrees 40 degrees, in the reflective display unit the retardation of the liquid crystal layer is 230nm or more, in the range below 300 [mu] m, retardation of the liquid crystal layer in the transmissive display section is larger configuration than the retardation of the liquid crystal layer in the reflective display section. Bright in a wide range of light environment spanning under direct sunlight from the dark, a wide display can be obtained color reproduction range.
