Patent ID: 7518697

Claim:
A liquid crystal display device comprising, in a display region, a plurality of columnar spacing structures provided between a pair of substrates; wherein each of the plurality of columnar spacing structures including at least one resin layer; wherein a spring modulus Kps of the columnar spacing structures per unit area is within a range of no less than 0.48 mN/μm 3 and no more than 0.72 mN/μm 3 ; an area ratio P of the columnar spacing structures is within a range of no less than 0.00016 and no more than 0.00493; and a spring modulus Kpt per unit area of display region is within a range of no less than 0.00008 mN/μm 3 and no more than 0.00237 mN/μm 3 , the spring modulus Kpt being defined as Kps×P=k×n/S, where k is a spring modulus of each columnar spacing structure (mN/μm); S is an area of a display region; and n is a number of columnar spacing structures in the display region.
