请参阅图1，本发明佳实施方式提供一种反光片及及设有所述反光片的背光模组。所述反光片10包括底板11、设于底板11周缘的侧板12及平行于所述底板11设置的固定板13。所述固定板13由所述侧板12远离底板11端部向底板11方向弯折延伸形成，所述底板11、侧板12及固定板13围成收容槽。所述背光模组还包括导光板20、背光源30及光学膜片40。所述导光板20包括通槽21、出光面22及位于通槽21内侧的入光面23。所述背光源30包括基板31及设于基板31上的灯源32。所述导光板20与所背光源30及光学膜片40装于所述收容槽内，所述导光板20装于底板11上，所述灯源32位于通槽21内与入光面23相对，所述光学膜片40装于出光面22上，所述固定板13抵压所述基板21及光学膜片40边缘。
进一步的，所述侧板12朝向所述底板11的表面以及底板11的表面均为反光面。本实施例中，所述反光片10由板体弯折形成，其底板11用于将导光板20露出的光线反射回导光板20内，而侧板12设为反光面可以将灯源32没有进入入光面23的光反射进入入光面23，提高光源利用率。
请参阅图2与图3，所述导光板20为矩形板体，其设有两个相对的长边 24及连接两个长边24的短边25。所述出光面22上靠近短边25的位置设有所述通槽21。本实施例中，所述通槽21垂直于所述出光面22设于所述导光板20一侧并贯穿导光板20。通槽21为数个且沿着平行于短边25的直线排列。所述入光面23为所述通槽21的远离端边的槽侧壁。
所述基板31为条形板体，所述灯源32的数量与所述通槽21数量相同且位置相对应。数个灯源32间隔排列于所述基板31的表面。所述光学薄膜40为多层膜叠加形成，其贴于所述导光板20的出光面22上。当导光板20、背光源30及光学膜片40收容于反光片10形成的收容槽时，所述底板11、导光板20及光学薄膜40依次叠加设置，所述灯源32收容于所述通槽21内，所述基板31抵持于导光板20的通槽21的周围。所述固定板13将基板31及光学薄膜40限位于所述收容槽内。

进一步的，所述导光板20的出光面22上放置光学薄膜40的部分为凹部28。本实施例中，所述凹部28设于所述出光面22中部，使出光面22周缘形成凸台状，同样是为减小背光模组的厚度，而且凸台用于支撑所述基板31及固定板13，所述基板31与凸台之间通过双面胶固定。
本发明的背光模组直接利用反光片10作为承载体来承载及固定导光板20、背光源30及光学膜片40，节省胶框的制作，避免成型的难度，同时保证背光模组实现窄边框的设计。而且所述反光片10的固定板13在不增加边框宽度的前提下有足够的面积来固限位导光板20、背光源30及光学膜片40，保证 了背光模组的组装质量。
请参阅图4，本发明还提供一种显示装置，所述显示装置包括所述的背光模组和显示面板60，所述显示面板60装于所述背光模组上与所述反光片10的固定板13背向底板11的表面抵持。所述显示面板60与固定板13之间通过双面胶70固定。由于节省了胶框，即减小了背光模组边框宽度，而固定板有足够的长度工双面胶来固定所述显示面板60，保证了背光模组与显示面板的组装稳定性。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
