Abstract: A light-emitting label (100, 210, 300, 400, 500) and a light-emitting label system (200) comprising same. The light-emitting label (100, 210, 300, 400, 500) comprises: a back plate (110, 310, 410, 510), at least one battery (120, 320, 420, 520), a light guide plate (140, 340, 440, 540), a flexible printed circuit (150, 350, 450, 550), and a pattern layer (160, 360, 460, 560). The flexible printed circuit (150, 350, 450, 550) comprises a substrate surface (152) and an electrically-conductive surface (154) comprising a plurality of light-emitting diodes (1542) arranged thereon. The light guide plate (140, 340, 440, 540) comprises a front light guide surface (142) and a rear light guide surface (144) opposite thereto. The pattern layer (160, 360, 460, 560) fixes the flexible printed circuit (150, 350, 450, 550) onto the front light guide surface (142), and the back plate (110, 310, 410, 510) seals the at least one battery (120, 320, 420, 520) onto the rear light guide surface (144).
