<p>A luminescent sheet and a method for producing the same are provided to prevent reduction of luminescence by adjusting a pore diameter and a pore area ratio in perforating. A luminescent sheet is formed by perforating a sheet to generate luminescence. The sheet is an electroluminescent sheet. A pore area ratio is 5 to 80%. A pore diameter in a perforating process is 0.1 to 20mm and a length of an interval between centers of pores is 0.2 to 50mm. The luminescent sheet is perforated in a matrix pattern through drilling, heated-needle processing, punching, flat die cutting, rotary die cutting, or laser processing.</p> |
