Abstract

The invention discloses a display device which sequentially comprises a thin film transistor substrate, a light-emitting layer, a color filter layer and a polarizing layer, a plurality of light-emitting devices of the light-emitting layer correspond to a plurality of color resistance units of the color filter layer in a one-to-one mode, and the shapes and the sizes of projections of the corresponding color resistance units and the light-emitting devices on the display device are the same. According to the display device provided by the invention, the light transmission paths from the light emitting device to the color resistance unit are parallel, light divergence is reduced, light interference and light leakage phenomena are reduced, color shift caused by wavelength shift is reduced, andthe display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In the display device of the prior art, the output light of the backlight is filtered by the color filter layer to provide a colored light source, wherein the size of the color resistance unit of the color filter layer is larger than that of the light emitting device of the backlight (usually LED (Light Emitting Diode) is selected. , Light-emitting diode) The size of the light output surface of the light-emitting device) makes the light path from the output light of the light-emitting surface of the light-emitting device to the color resistance unit have divergent light, and the wavelength of the divergent light has a certain offset, which will cause the display device The output color shifts, reducing the display quality. Contents of the invention [0003] In view of the above problems, the purpose of the present invent...
