## Abstract

A display is provided. The display includes a metal back plate, a plastic frame, a backlight optical module and a liquid-crystal module. The metal back plate includes a plurality of metal wedging portions and a first side. The plastic frame is combined with the metal back plate by injection molding. The plastic frame includes a plurality of plastic wedging portions. The plastic wedging portions wedge the metal wedging portions. The plastic frame defines a recess on the first side of the metal back plate. The backlight optical module is disposed in the recess. The liquid-crystal module covers the backlight optical module and is connected to the plastic frame.

## Claims
