Liability of shareholder in a Thai limited Company

i'd like to understand the limitation of liability for a minority shareholder in a Thai business limited Specifically i'd like to understand whether a shareholder can be held accountable for the actions of the board of directors. if shareholder can be held responsible for directors actions then to what level from what i have read so far i think that the shareholders can only be held accountable up to the amount of "unpaid" shares that they own, just like some confirmation that this is actually correct Thanks
