• 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 ELEMENTS, SYSTEMS, OR APPARATUS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of performing three-dimensional display using a liquid crystal lens, in which a mechanical strength and a liquid crystal lens effect are both satisfactorily obtained.SOLUTION: A liquid crystal lens 10 is bonded on an upper polarization plate 111 of a liquid crystal panel 1000 by an adhesive 70. The liquid crystal lens 10 includes an upper substrate 20, a lower substrate 30, and a liquid crystal layer 40 held therebetween. The thickness of the upper substrate 20 of the liquid crystal lens 10 is larger than 0.2 mm and equal to or smaller than 1.5 mm, and larger than the thickness of the lower substrate 30 of the liquid crystal lens 10. Preferably, the thickness of the upper substrate 20 of the liquid crystal lens 10 is larger than the sum of the thicknesses of the lower substrate 30 of the liquid crystal lens 10 and the liquid crystal panel 1000. Thus, there can be achieved a liquid crystal display device in which a mechanical strength and a liquid crystal lens effect are both satisfactorily obtained.
