A light guide plate having micro-reflectors is to increase luminance of the light guide plate by changing light route. The light guide plate includes an incidence plane, an illuminating plane, and a bottom. Each of the micro-reflectors is disposed at the bottom and intersected with the light guide plate in a direction heading for a recess provided at the bottom of the light guide plate, and comprises a light reflection plane located between the incidence plane and the illuminating plane to define an angle theta. The light reflection plane is an arc quadrilateral or a sector when observed from top of the illuminating plane. The arc quadrilateral has two concentric arc sides parallel with each other.
