<p>PURPOSE:To enable the observation of peripheral part of a display element which is as slender as >=30cm with the same good contrast as in the parts around the central part by varying the orienting angle of the liquid crystal molecule near the central part in the display part in the long axis direction thereof and the orienting angle near the peripheral part. CONSTITUTION:The inside wall surface of a front substrate 13 of a plastic material constituting a liquid crystal display element is subjected to the horizontal orientation treatment in the directions shown by arrows Fa', Fb', Fc' according to the positions of a central part A', and peripheral parts B', C', at slightly varied angles Qa', Qb', Qc'. On the other hand, the inside wall surface of a rear substrate 14 is subjected to the horizontal orientation treatment in the directions shown by arrows Ra', Rb', Rc' according to positions A', B', C' at slightly varied angles Pa', Pb', Pc'. Then, the direction of the displayed characters, etc. where the characters, etc. are visible with the best contrast directs to the observer side irrespectively of display positions.</p> |
