Abstract:
A liquid crystal display comprising:first and second substrates each having a display and a non-display region and being disposed to face each other; a plurality of columns each comprising a spacer disposed in the non-display region of at least one of the first and the second substrates and being formed of photosensitive resin which regulates a cell gap between the first and the second substrates; and liquid crystal sandwiched between the first and the second substrates, wherein each of said spacers has a dynamic hardness value (DH) from 26 to 30, which is obtained by the following formula: DH=KÃ—Pmax/hmax2, wherein DH is dynamic hardness, K is a constant value assigned to the indentator used to test the liquid crystal display, Pmax is maximum load, and hmax is the total maximum variation obtained by adding the measured elastic deformation and plastic deformation under load,and wherein each of said spacers has a hardness value of plastic deformation (HV) from 38 to 46, which is obtained by the following formula:HV=KÃ—Pmax/hr2, wherein HV is hardness of plastic deformation, K is a constant value assigned to the indentator used to test the liquid crystal display, Pmax is maximum load, and hr is measured variation when the tangent in the maximum variation point of a curb has no load in the case of unloading.
