• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PURPOSE: To solve the difference of retardation between a casing part and a driving area while keeping the reduction of between luminance and to improve display quality without optical omission at an effective area. CONSTITUTION: As for a liquid crystal display device where a packaging part 105 connected to an outer driving circuit through a pulling part 102 is formed at the periphery of the driving area 101 of two substrates having a liquid crystal layer between and provided with an electrode and the effective area 103 is formed of the driving area 101 and the casing part 104 positioned at the inner peripheral edge of the pulling part 102, the survival rate of the electrode of the casing part 104 is made to be nearly the same as the driving area 101 and electrode shape other than the casing part 104 of the pulling part 102 is changed.
