Which phenomenon causes reduced LCD brightness under strain?

💡 Explanation

Strain alters the liquid crystal alignment, because stress-induced birefringence changes polarization and blocks light transmission; therefore brightness decreases rather than changes arising from electrical effects such as leakage or piezoelectric effects.
