unashamed
靦 centers on a lack of shame or embarrassment, describing someone who is unashamed or brazen-faced.
靦 combines 面 (face) and 見 (see), suggesting a face that is seen openly without shame. The exact historical development is uncertain, but the component combination directly reflects the meaning of being unashamed.
The left side is 面 (face) and the right side is 見 (see). Imagine a face that is seen by everyone without any sign of embarrassment—completely unashamed.
For テン, picture an unashamed person standing under a tent (テン) with their face fully visible, not caring who sees them.
