3 	Transparent micro-capsules
4 	Positively charged white pigments
5 	Negatively charged black pigments
6 	Transparent oil
7 	Electrode pixel layer
8 	Bottom supporting layer
9 	Light
10 	White
11 	Black
Since the eInk substrate is not in the light path, it has no effect on the display. Please also note that item 1 labelled as the upper layer will have various layers above it such as the light guide, capacitive touch screen, matte surface layer, etc.
I assume that drawing comes form wikipedia, which does not state it's source. It's pretty good overall, but the depiction of "black" light reflecting is cringe worthy.
