Light guide plate, backlight module and display

The invention relates to a light guide plate, a backlight module and a display. The light guide plate is used in cooperation with a luminous source to convert light emitted by the luminous source into plane light and comprises a body and a reflection part, the side face of the body is defined as a light incident face, the top face of the body is defined as a light emergent face, and a total reflection face with the total reflection effect is formed on the reflection part. The total reflection face is connected with the light incident face and the light emergent face, and the thickness of the body is greater than the height of the light emitting source in the thickness direction of the body, so that the light guide plate has the efficacy of reducing energy loss and improving light emitting efficiency. 本发明涉及导光板、背光模组及显示器。该导光板用以与发光源配合使用以将该发光源所射出的光线转化为平面光线，该导光板包含本体及反射部，该本体的侧面被定义为入光面，该本体的顶面被定义为出光面，该反射部上形成有具全反射效果的全反射面，该全反射面连接该入光面与该出光面，其中，在该本体的厚度方向上，该本体的厚度大于该发光源的高度，由此可提供一种可减少能量损失并提升发光效率的导光板。
