Abstract

A tiled display device includes: a first display device including: a first display substrate having a plurality of light emitting areas; and a second color conversion substrate comprising a plurality of light transmitting areas respectively corresponding to the light emitting areas and comprising a light scattering material and a plurality of light blocking areas between the light transmitting areas; a second display device comprising a second display substrate and a second color conversion substrate, the second display device being at a side of the first display device; and a light scattering member between the first display device and the second display device and comprising a light scattering material, wherein an external light reflectance of the light scattering member is higher than an average value of an external light reflectance of the light transmitting areas and an external light reflectance of the light blocking areas.

Description

technical field [0001] The invention relates to a spliced ​​display device. Background technique [0002] With the development of the information society, demands on display devices for displaying images are increasing in various forms. For example, the display device is applicable to various electronic devices such as smart phones, digital cameras, notebook computers, navigators, and smart TVs. The display device may be a flat panel display device such as a Liquid Crystal Display Device, a Field Emission Display Device, or an Organic Light Emitting Display Device. Among these flat panel display devices, the light emitting display device includes a light emitting element capable of making each of the pixels of the display panel emit light by itself, so that an image can be displayed without the display panel having a backlight unit for supplying light. [0003] In the case of manufacturing a display device in a large size, due to an increase in the number of pixels, the de...
