This invention relates to an LED strip fixed structure and an LCD, wherein the LED strip fixed structure includes a back panel, an LED strip and a strip fixed element, a groove used for accommodating the LED strip is formed on the strip fixed element, and light holes used for accommodating LEDs on the LED strip are formed in the groove; the fixed element is used for containing the LED strip, and is fixedly connected with the back panel. In this invention, the fixed element for accommodating the LED strip is fixed on the side wall of the back panel, so as to increase the heat dissipation channel of the LED strip; instead of arranging heat dissipation aluminum extrusion between the LED strip and the back panel, and so as to reduce the quantity of connecting pieces such as connecting screws. This invention improves the effect of heat dissipation at the backlight part of the LCD, and meanwhile simplifies the installation structure of the LED strip and lowers the cost.
