Description

Display device Technical Field The invention relates to a display device (DISPLAY DEVICE). Background With the development of the information society, the demand for display devices has increased in various forms, and various display devices such as LCDs (Liquid CRYSTAL DISPLAY DEVICE: liquid crystal displays), OLEDs (Organic LIGHT EMITTING Diodes), micro LEDs (Micro LEDs: micro light emitting Diodes) and the like have been studied and used in recent years. Among them, the LCD panel has a TFT substrate and a color substrate facing each other with a liquid crystal layer interposed therebetween, and can display an image using light supplied from a backlight unit.
