The first sidewall and the second sidewall are spaced apart from each other to form a receiving space. The first supporting wall connects an end of the first sidewall and an end of the second sidewall. The second supporting wall extends away from the second sidewall and connects to the other end of the first sidewall. The liquid crystal panel is supported on a side of the first supporting wall that faces away from the first sidewall and the second sidewall. The light guide plate is supported on a side of the second supporting wall that faces towards the liquid crystal panel. The light source is disposed inside the receiving space. The first sidewall is formed with a through-hole for allowing light rays generated by the light source to pass therethrough into the light guide plate. With the aforesaid arrangement, the metal backplate and the plastic mid-frame used in the prior…
