Abstract: Provided is an LED display device that can improve utilization efficiency of light with a simple configuration having a small number of components. The LED display device includes an LED array formed by arranging a plurality of light emitting diodes that emit excitation light having a wavelength of less than 420 nm, on a substrate; a color conversion layer; a wavelength-selective reflection layer disposed on a side opposite to the LED array; and an RGB reflection layer disposed on an LED array side with respect to the color conversion layer, in which the color conversion layer is disposed at each of positions corresponding to the light emitting diodes of the LED array, and includes a red color conversion region emitting red light, a green color conversion region emitting green light, and a blue color conversion region emitting blue light, which are excited by the excitation light, and a partition wall that divides each region, a height h of the partition wall is 20 μm or less and a ratio w/h of a width w between partition walls to the height h is 2 or more, the wavelength-selective reflection layer selectively reflects light having a wavelength of the excitation light and is integrally formed at positions corresponding the respective regions, and the RGB reflection layer reflects at least light having a wavelength of 450 nm to 650 nm.

Abstract: A liquid crystal display device includes: a liquid crystal layer; a first substrate including thin-film transistors configured to drive liquid crystal molecules of the liquid crystal layer, at least one type of electrode, and an insulating film, at least a part of which is in direct contact with the liquid crystal layer; and a second substrate disposed so as to be opposed to the first substrate with the liquid crystal layer interposed therebetween. One of the at least one type of electrode is disposed on the insulating film. The insulating film has a function of aligning the liquid crystal molecules of the liquid crystal layer. The insulating film formed on the thin-film transistors also serves as an alignment film configured to align the liquid crystal molecules and the structure is simplified more than before. The manufacturing process is also simplified more than before.
