• 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

PROBLEM TO BE SOLVED: To prevent the display of a frame-like abnormal frame on the outside of an effective display area of a liquid crystal display panel even when burrs are generated in a dicing step of a liquid crystal display apparatus. SOLUTION: In the liquid crystal display apparatus provided with the liquid crystal display panel comprising a pair of substrates consisting of first and second substrates and a liquid crystal layer held between the pair of substrates: the first substrate has a common electrode on a surface opposed to the second substrate; the second substrate has a plurality of reflection electrodes formed on a surface opposed to the first substrate, a first conductive film arranged so as to surround these reflection electrodes and a second conductive film arranged so as to surround the periphery of the first conductive film; common voltage to be applied to the common electrode is applied to the first conductive film; and reference voltage (GND) is applied to the second film.
