<p>Disclosed is a liquid crystal display device which can assure a desired cell gap at the time of heat contact bonding involved in the assembling of cells in a liquid crystal display device and, after the preparation of liquid crystal cells, has excellent reliability, can cope with an increase in cell thickness at high temperatures, and can inhibit a foaming phenomenon in a liquid crystal layer at low temperatures. The liquid crystal display device comprises: two substrates; a liquid crystal sandwiched and supported between the two substrates; and spacers, for maintaining a predetermined substrate-substrate spacing, provided on at least one of the substrates in its portions where the liquid crystal is sandwiched and supported, the spacers being formed of a photocured resin layer, the photocured resin layer having such properties that, as determined by the measurement of dynamic viscoelasticity in the temperature range of -40 DEG C to 80 DEG C, the storage modulus (E') is not more than 5.0 x 10<9> Pa with the loss tangent ätan delta = E'' (loss modulus)/E'ü being not more than 0.1 and, as determined by the measurement of dynamic viscoelasticity in the temperature range of 120 DEG C to 180 DEG C, the storage modulus (E') is not less than 5.0 x 10<7> Pa with the loss tangent ätan delta = E'' (loss modulus)/E'ü being not more than 0.3, or alternatively the photocured resin layer having a Young's modulus, derived from a stress-strain curve, of not more than 10,000 MPa at 25 DEG C and not less than 10 MPa at 150 DEG C or a dynamic hardness of 30 to 60 under load. <IMAGE></p> |
