Which phenomenon disrupts LCD display clarity because of stress?

A)Stress-induced birefringence
B)Chromatic dispersion
C)Electromagnetic backscatter
D)Thermal lens effect

💡 Explanation

Stress induces anisotropy which rotates polarized light within the liquid crystal layer through stress-induced birefringence; therefore contrast decreases, rather than remaining constant or increasing chromatic dispersion or thermal effects, which have very different mechanisms.
