"Did you see the show?"
Translation:An bhfaca tú an taispeántas?
No. The noun taispeantas, is associated with the verb taispeáin, meaning "to show", or "to display", or "to exhibit". Clár means "board", but it also used for a table or list, so it has come to mean "programme (of events)", and in much the same way that in English "a TV programme" has come to mean a single "show", rather than a list of all the shows available, clár in now used for a radio or TV programme.
