The present invention relates to a shelf for a refrigerator, and a refrigerator having the same. A shelf for a refrigerator according to the present invention comprises a support plate 22 having an upper surface on which an article is to be put; a frame 24 formed to correspond to the shape of a periphery of the support plate 22 and having, at an inner side thereof, a coupling portion 30 to which the support plate 22 is coupled to the coupling portion 30 by means of a bonding member 32; and a fixing device for fixing the support plate 22 to the coupling portion 30. At this time, the fixing device may comprise a fixing member 34 having a supporting protrusion 34b penetrating though a sidewall of the frame 24 to support the support plate 22 from below. Alternatively, the fixing device may comprise an elastically deformable resilient hook and a fixing protrusion formed to face the resilient hook all of which are provided on the frame. With the shelf for a refrigerator according to the present invention constructed as above, there are advantages in that the shelf has a secure coupling structure, the process of coupling the components of the shelf is simplified, the shelf has improved durability, and production costs are reduced.

The present invention is directed to a liquid crystal display device and a method for driving the same for a fast transition into a bend state at initial operation such as immediately after power is inputted in a liquid display device with an OCB mode. According to one feature of the present invention, as power is inputted, a timing controller controls to output at least one of a gate voltage for a scan signal, a data voltage for a picture signal, and a driving voltage for a backlight by outputting a first switching signal to a switching unit, and controls to output one of an external bias voltage and a common electrode voltage by outputting a second switching signal to the switching unit so that fast transition into bend state of liquid crystal arranged in a LCD panel is accomplished. As a result, by applying a voltage of less level than that of the typical common electrode voltage to the LCD panel, as DC voltage of at least 10 volt to 20 volt is applicable to a common electrode, time for transition into bend state can be reduced at initial operation of the liquid crystal display device using the LCD panel with OCB mode.
