Curved-surface LCD device

The invention provides a curved-surface LCD device. The curved-surface LCD device comprises a backlight module (2), a sealant frame (4), an LCD panel (6) and a front frame (8). The backlight module (2) comprises a back plate (22), an arc-shaped LGP (24), a backlight source (26) and a heat dissipation plate (28), wherein the arc-shaped LGP (24) and the backlight source (26) are arranged in the back plate (22), and the heat dissipation plate (28) is used for installing the backlight source (26). The heat dissipation plate (28) comprises a supporting part (282) and an installation part (284) which is obliquely connected to the supporting part (282), wherein the supporting part (282) is installed on the back plate (22), and the backlight source (26) is installed on the installation part (284). The front frame (8) comprises a front plate (82) and a side plate (84) connected to the front plate (82). An installation piece (286) is arranged on the installation part (284) and extends towards the side plate (84). The installation piece (286) is connected to the side plate (84), so that the front frame (8) and the heat dissipation plate (28) are connected together.
