• displayed: This is a synonym of "showed", meaning to exhibit or make visible.
• concealed: This means to hide, keep secret, or prevent from being known or seen. This is the exact opposite of showing or revealing something.
• battled: This means to fight or struggle against, which is unrelated to showing or hiding disbelief.
• marked: This means to indicate or designate, which does not represent the opposite of showing.

Therefore, concealed is the opposite in meaning to the word "showed".
