場 combines 土 (earth, ground) with 昜, which likely contributes the sound and the idea of an open or spread-out area. Together they suggest a piece of ground used as a place or location.
The left side is earth 土, and the right side 昜 looks like a sun 日 over a spread-out shape. Picture a sunny patch of ground that becomes a gathering place.
For ジョウ, imagine a show being set up at a location: show -> ジョウ, and the place becomes a stage.
