Abstract
A backlight module includes a plurality of light emitting elements and a plurality of lens structures. Each light emitting element has a light emitting surface. The plurality of lens structures covers each light emitting element. Each lens structure has a light exit surface having a curved shape. The light exit surface has a vertex and a focal point located between the vertex and the light emitting element. The distance between the focal points of two adjacent lens structures is a first distance, and each light emitting element has a light emitting width. The ratio of the first distance to the light emitting width is greater than or equal to 10.
