Abstract: Image display apparatus includes liquid crystal cell, flat plate-shaped back frame, light guide plate, and a pair of support mechanisms. The pair of support mechanisms are fixed to back frame in positions at which light guide plate is clamped at both sides that intersect a first axis (X-axis). The pair of support mechanisms each includes movable component that supports light guide plate, body component that movably retains movable component, and elastic member that pushes movable component toward opposite support mechanism. Protrusion is disposed on movable component, and engagement section with which protrusion engages is disposed on light guide plate. Engagement section includes tab that is formed outwardly on an end surface of light guide plate, and notch disposed on tab and engages with protrusion.
