@TK. I've added three of them in the Gallery, please fell free to use them if you like.

So... It take way too much time to start using eagle. What a nightmare for a such simple board:

Note that i havent check the reverse/mirror pin thing yet because I have a question first: how to make the upper solder pads to touch the border of the board ? This way it will be possible to solder this board to a 90° angle to the LCD with no wire.
And then I will find how to add the ribbon connector schematic..

Maybe you can get it to a single layer by routing through the SIP header. 

For pads to the edge, you could consider a castellated pad/via. Normally the fab will charge extra for it. I'm not sure if it's a good idea mechanically; the simple pin header would be stronger. Or maybe I don't understand your idea.

I've done exactly this (with the board outline at the edge) at OSHPark. About half of my boards had missing copper though, as I suppose the router can pull the plating off.

Yes ! Theses are good tips !

I'll try by myself now with standard connectors. I have to learn and it's a useful exercise. And with the files you provided it will help too. Thanks !

Take a look:

There was no chance that I could find it with the search function but... By looking deeper and deeper in the forum I fall into this tread.

Ah right, these can be very confusing! Also, the way CMOS labels power connections as Vcc Vdd Vss etc. can also lead to mistakes.

I didn't check the pin compatibility (please check!), but this PCB might help:
