A broadsheet is a newspaper printed on large sheets of paper. In Britain especially, the word also came to mean a serious paper — long articles, politics, “quality” news — as against a tabloid, which is smaller and often louder. The Times and the Guardian were classic broadsheets. Though actually many of those papers later made their pages smaller so people could read them on a train, but speakers still call them broadsheets when they mean the serious type, not the physical size. From broad + sheet. Older English also used broadsheet for any large printed sheet, like a song or a public notice on one page; you will meet that meaning in history more than in a shop. The word can be a noun (a broadsheet) or an adjective (a broadsheet paper).
