经典 (jīngdiǎn) as a noun means 'the classics' — enduring works of literature/art; as an adjective it means 'classic, of the highest standard'. It differs from 典型 (diǎnxíng 'typical, representative'), which just means a common example, and from 古典 (gǔdiǎn 'classical'), which specifically refers to ancient or traditional styles.
