Why led be is dimmer in pin 2 than in pin 13 ?

Surely I dont use resistor for that two cases...

Here I attach, you see the led even like turned off...
Heuu, I found another problem, that my 7segment is hullaballo, dont work properly...

It is so weird, the 7 segment on when I move my finger near without touching the cable, what a mystic!
I dont have any sensor around there....
I move my finger to the shift register IC 74HC595, and the 7segment lights on randomly...
Can you help with this?
