The kanji 県 is a phono-semantic compound (形声文字, keisei moji). The left part is "目" (me, eye), which gives the meaning. The right part is "糸" (ito, thread), which gives the sound. Originally, the right side of the character was a component to mark the boundaries of a territory or area, similar to a thread marking the extent of the land. Later, the character became associated with administrative districts, or prefectures, that also had boundaries. The "目" (me, eye) component suggests "to observe" or "to oversee", which relates to the administrative function of a prefecture.
