i have some problem of use of 8051. The problem is I have not enough 8051 pins to use .Therefore i want to use connected cd4094be . i want to ask my connection of 8051 and 4094 is right ? (aboved picture) Any mistakes >? THANK YOU

 

Your connections are OK. (You didn't show power and ground on the 4094 or ground on the 8051, but will assume you know that).

But, with a 5 volt power supply, the CD4094 can only source or sink around 0.88ma per output according to my datasheet. That's not enough current for typical LED's.
Use a type 74HC or 74HCT4094 instead. Those can source or sink at least 4ma, and use a 5 volt power supply.

If you must use a CD4094 then a buffer will be needed on the outputs to drive LED's.

 

Consider using 74HC595 shift registers:

If you need to sink more current than a 74HC595 can handle, consider using STPIC6D595 power shift registers:
