The window shade (100) has collapsible shade rows (102), each adjustable from a closed state to an opened state by an operating mechanism, and including a stiff first transverse region (104) and an opposed second transverse region (106) having a stiffened edge portion (108). The operating mechanism causes the narrowing of the rows by drawing the first and second transverse regions closed together. The operating mechanism further causes the rows to be pivotally rotated in the window shade. When in the closed state, the window shade includes no or minimal gaps between the rows so that light is substantially or completely blocked. Securement and opening members (112,114) of the operating mechanism are concealed from view when observed from the front or face of the window shade. |
