<p>The present invention provides a self light-emitting retroreflective sheet including a light-transmitting retroreflective element including a plurality of prismatic projections, a lining film, and an electroluminescence device. The lining film includes a light-transmitting film which has sealing projections on one of its surfaces so that the prismatic projections are confined within a plurality of sealed cells formed by the sealing projections. In the sealed cells, a surface of the prismatic projections interface with air so as to increase light-emitting luminance and improve its uniformity.</p> |
