摘要：
说明一种显示装置、尤其是显示屏(4)的显示屏单元(6)，具有用于显示屏(4)的背景照明的背景照明单元(8)；布置在背景照明单元(8)的辐射方向上的并至少部分地覆盖背景照明单元(8)的偏振滤光镜(10)；布置在偏振滤光镜(10)的背向背景照明单元(8)的那侧上的液晶层(14)；包括至少一个滤色镜并布置在液晶层(14)的背向背景照明单元(8)的那侧上的滤光装置(16)，其中背景照明单元(8)包括发射蓝色光的发光二极管(22)，并且其中在发射蓝色光的发光二极管(22)后面布置至少两个不同的磷光体，这些磷光体吸收发光二极管(22)的蓝色光并再发射互相不同颜色的光，所述互相不同颜色的光与发光二极管(22)的蓝色光混合成白色光(36)。
摘要（英）：

Disclosed is a display device, especially a screen unit (6) of a screen (4), comprising a backlighting unit (8) for backlighting the screen (4), a polarizing filter (10) that is arranged in an emitting direction of the backlighting unit (8) and at least partially covers the backlighting unit (8), a liquid crystal layer (14) that is arranged on the side of the polarizing filter (10) facing away from the backlighting unit (8), and a filter arrangement (16) that encompasses at least one color filter and is arranged on the side of the liquid crystal layer (14) facing away from the backlighting unit (8). The backlighting unit (8) comprises a blue light emitting diode (22), downstream of which at least two different phosphors are arranged that absorb the blue light of the light emitting diode (22) and re-emit light which has different colors and mixes with the blue light of the light emitting diode (22) to generate white light.
