Hi, I'm working on a 10 digit display for a countdown and am new to electronics. After doing some research, I build up this diagram of a circuit and was wondering if anyone could confirm me if it could work? I also don't know which value should the resistors and capacitors have? I also left the data sheet of my 7-segments.

thanks for the help!

That won't work.  To use a 595 with LEDs you need one resistor per LED. 

Be sure your LED's are Common Cathode if you are tying the Common to ground.  If you accidentally get Common Anode displays, just tie the common pins to +5 and the segment will light when the output pin is LOW.
