Other forms: displayed, displays, displaying
A display is a set of things arranged so that people will look at them. Cakes behind glass in a bakery, trainers stacked up the back of a shop window, medals laid out on velvet in a museum case.
It is also the screen you are reading this on — a cracked display, a six-inch display, the display on the cooker that has shown the wrong time since March. Events take the word as well: a firework display, a flying display, a display of horsemanship. So does behaviour, especially behaviour performed for an audience, as in a display of temper or a public display of affection. As a verb it means to put on view: the shop displays its prices in the window, the sign displays the platform number, and male birds display to attract a mate. On display is the fixed phrase — the crown jewels are on display, and so, at a bad meeting, is somebody's ego.

Display comes from Middle English displayen, through Anglo-Norman despleier from Medieval Latin displicare, 'to unfold' — Latin dis-, 'apart', with plicāre, 'to fold'. A display is a thing unfolded: a banner shaken out so the whole army can see it. Deploy is the same word arriving by another road, which is why armies deploy and shops display.
