The first alleged parts from the larger 5.5" iPhone 6 have been shared by 9to5Mac. The image shows the front and back of an LCD backlight panel that measures ~14 centimeters or ~5.5 inches diagonally.
We've already seen some possible part leaks for the 4.7" model, but this is the first part leak for the 5.5" model. Reports had originally suggested the 5.5" model would be released after the initial 4.7" iPhone launch. More recently, however, we've heard that Apple may have solved whatever production challenges they ran into with the 5.5" model.
Possible parts for the 4.7" iPhone 6 model that have leaked include the front panel, batteries, rear shell and chassis molds. Meanwhile, the same LCD backlight for the 4.7" model was photographed in May. For comparison:
