A window blind 10 includes top and bottom beams, and many slats disposed therebetween. The top beam 30 has two opposite lateral holes 34. The window blind 10 further includes a slat folding transmission device 40 having a cord rolling member 41 5 disposed in the top beam 30, and two opposite lift transmission cords 49 passing through the lateral holes 34 of the lateral plates 33 of the top beam 30 respectively. Two ends of each lift transmission cord are connected with the bottom beam 20 and the cord rolling member 41 respectively, so that the two lift transmission cords 49 can pull the bottom beam 20 simultaneously when being rolled by the cord rolling member 10 41, thereby moving the bottom beam 20 upwardly to fold up the slats. Therefore, the slats of the window blind 10 of the invention need no processing and keep complete in structure, thereby providing good effect of blocking out the light when being adjusted to the inclined condition.
