PURPOSE: To substantially eliminate the unequal display by the heat transmitted from outside by designing a liquid crystal display element in such a manner as to attain the uniform product of the refractive index anisotropy of a liquid crystal compsn. and the thickness of a liquid crystal layer. CONSTITUTION: This liquid crystal display element is driven under prescribed standard conditions by maintaining a region A sprayed with spacers 8 at 20 deg.C and a region B sprayed with spacer 9 at 40 deg.C in such a manner that the products,Δn(T).d of the respective refractive index anisotropiesΔn of the region A sprayed with the spacers 8 and the region B sprayed with the spacer 9 and the thickness (d) of the liquid crystal layer are substantially equaled. Consequently, the unequal display in the parts where unequal temps. arise is drastically lessened and homogeneously displayed images are obtd. in the effective display region. At this time, the ratio (d2-d1)/d1 of the absolute value difference (d2-d1) between the thickness d1 of the liquid crystal layer of the region A and the thickness d2 of the liquid crystal layer of the region B and d1 is maintained within a range of 0.3, by which the surer effect of substantially eliminating the unequal display by the temp. distribution is obtd.
