A window shade (100) includes a reel (132) and an aperture control module (200) respectively assembled with a head frame (102), and a panel assembly (104) including transversal vanes (120) respectively connected with two panels (116, 118) of the panel assembly (104). The reel (132) is rotatable to wind and unwind the panel assembly (104). The aperture control module (200) includes a positioning arm (202) connected with a rubbing roller (136), and is operable to rotate the rubbing roller relative to the positioning arm and to displace the positioning arm and the rubbing roller between two positions, the rubbing roller (136) being displaced away from a sidewall (160) of the head frame (102) in a first position and pressing the panel assembly (104) against the sidewall (160) in a second position, the rubbing roller (136) being further rotatable relative to the positioning arm (202) in the second position to cause relative sliding between the two panels (116, 118) for switching the panel assembly (104) from a closed state blocking light passage to an open state allowing light passage.
