So ODF specifies that the <draw:layer> tag can have a draw:display attribute with values that change how it appears on screen or outputted to the printer and these values are being ignored on import. We do support the functionality for the 'none' value, which is equivalent to making the layer invisible, but not sure about the 'printer' (only show it when printed) and 'screen' (only show it on the screen) values.

Indeed, the attributes draw:display and draw:protected have never been implemented. Instead the settings config:name="VisibleLayers" and config:name="PrintableLayers" and config:name="LockedLayers" are used with binary data.
Bug 53864 "Export ignores layer options 'printable' and 'visible'" could be solved by another flag leading to 2^4 combinations, or the export is bind to one of the existing states. In this case I suggest to use printable.
We need no additional flag but only an export to the ODF attributes instead of writing it to binary(!) private config items.
The UI has checkboxes for visible, printable and locked. Checkbox 'visible' together with checkbox 'printable' results in the four attribute values 'always', 'none', 'printer' and 'screen' of attribute draw:display. And UI checkbox 'locked' corresponds directly to the values 'false' and 'true' of attribute draw:protected.
I'll try to find a solution.
Dear Regina Henschel,
This bug has been in ASSIGNED status for more than 3 months without any
activity. Resetting it to NEW.
Please assigned it back to yourself if you're still working on this.
I have suggested it as topic for the Hackfest in Hamburg 7./8. Apr. 2018.
Ok, assigning it back to you then...
Yes, I'm still working on it. Armin reviews my work, but he is currently very busy with all the regressions, therefore progress is slow.
The solution for this issue needs large changes in core.
Regina Henschel committed a patch related to this issue.
It has been pushed to "master":
tdf#101242 Support draw:display and draw:protect attributes of ODF
It will be available in 6.2.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
Affected users are encouraged to test the fix and report feedback.
Fixed in current master
