摘要:
A backlight device includes a housing, a light source, a diffuse plate and a fixing member. The housing has an open surface. The light source is arranged in the housing. The diffuser plate is arranged on the open surface of the housing and allows light emitted from the light source to pass therethrough while diffusing the light. The fixing member prevents the diffuser plate from bending in a direction in which light passes through the diffuser plate. A part of the fixing member has transmittance adjusted to substantially equalize luminance distribution of light passed through the diffuser plate.

A semiconductor memory device includes a memory cell provided at each of intersections of word lines and bit lines and connected to the corresponding word line and the corresponding bit line; an address transition detection circuit; an address latch circuit; an address decoder; a pre-charging circuit; and a control signal generation circuit. The address latch circuit is controlled by a bit line pre-charging signal, such that while the bit line pre-charging signal is at a first logic level, the address signal is input to the address latch circuit, and while the bit line pre-charging signal is at a second logic level, the input address signal is maintained by the address latch circuit. The address decoder is activated by the decoder activating signal. The address decoder is activated, the word line corresponding to the address signal is activated, and the memory cell connected to the corresponding word line is accessed.
