Certain patternable reflective films are used as masks to make other patterned articles, and one or more initial masks can be used to pattern the patternable reflective films. An exemplary patternable reflective film has an absorption characteristic suitable to, upon exposure to a radiant beam, absorptively heat a portion of the film by an amount sufficient to change a first reflective characteristic to a different second reflective characteristic. The change from the first to the second reflective characteristic is attributable to a change in birefringence of one or more layers or materials of the patternable film.

The invention discloses a QD CF substrate and manufacturing method thereof. The manufacturing method uses a patterned photo-resist layer as a masking layer to perform selective quenching on QD layer with a quencher to obtain selectively quenched QD layer, which simplifies QD CF substrate manufacturing process and reduces cost. The QD CF substrate does not use blue QD material in QD layer, but uses blue backlight and organic transparent photo-resist layer to improve light utilization efficiency and reduce material cost. The QD layer is a selectively quenched QD layer, and the portion of the QD layer located above the organic transparent photo-resist layer is quenched by the quencher, and will not emit light when excited by backlight. As such, the invention achieves using the QD material to improve color gamut and brightness, avoid color impurity at blue sub-pixels caused by light mixture, and the manufacturing method is simple.
