shining, bright
昭 centers on light that is clear and visible: something shining or bright. It is often used for obvious, manifest brightness rather than a soft glow.
昭 combines 日 (sun) with 召, which likely contributes the sound and the idea of calling or summoning, together suggesting the sun's light being called forth or made manifest.
The sun 日 on the left and 召 (which looks like a call or summon) on the right: imagine the sun being summoned to shine brightly, making everything clear and bright.
For ショウ, picture a bright show on stage: show -> ショウ, and the spotlight shines brightly on the performer.
