L in Death Note is the famous detective character, and people usually mean his personality type when they ask “what is L type.” He is commonly typed as INTP in MBTI discussions.

What that means

  • I = Introverted, so he keeps to himself.
  • N = Intuitive, so he looks at patterns and possibilities.
  • T = Thinking, so he relies on logic more than emotion.
  • P = Perceiving, so he stays flexible and exploratory.

In the story

L is portrayed as extremely analytical, cautious, and focused on solving the mystery of Kira rather than acting from emotion or a normal sense of justice. That lines up with why fans often read him as INTP.

Tiny note

If you meant “what is L” in a different sense, L is also just the character’s name in the anime and manga Death Note.
