Abstract

一种灯条、背光组件和显示显示装置。灯条包括基板(10)；第一金属层(11)，设置在基板(10)的第一侧，第一金属层(11)包括多个第一金属片段(111)，多个第一金属片段(111)沿灯条的长度方向间隔设置；第二金属层(12)，设置在基板(10)的第二侧，第二金属层(12)中包括多个第二金属片段(121)，多个第二金属片段(121)沿灯条的长度方向间隔设置；其中，相邻的两个第一金属片段(111)之间的间隔在基板(10)上的投影落入第二金属片段(121)在基板(10)上的投影内，相邻的两个第二金属片段(121)之间的间隔在基板(10)上的投影落入第一金属片段(111)在基板(10)上的投影内。其能够有效降低灯条发生断裂的可能性。
