appear, existing
顕 centers on becoming visible or manifest: something that appears, comes to light, or is clearly present. The 'existing' sense is the state of being apparent and undeniable.
顕 is the modern simplified form of 顯. The older form combines 頁 (head) with 㬎, which likely contributed the sound and the idea of something being visible or conspicuous. The modern left side 显 is a simplification.
The left side 显 looks like a sun 日 rising over a stand, and the right side 頁 is a head. Picture a head turning toward the bright sun as it appears over the horizon—something that was hidden becomes clearly visible.
For ケン, imagine Ken appearing suddenly in the doorway: Ken -> ケン, and his arrival makes his presence obvious.
