Abstract: A liquid crystal display device includes a thin film transistor (TFT) disposed on a substrate. The TFT is divided into pixel regions. Pixel electrodes are disposed in the pixel regions, respectively. The pixel electrodes are electrically connected with the TFT. A roof layer is disposed over the pixel electrodes. Fine spaces, which are spaced apart from each other, are each disposed between each of the pixel electrodes and the roof layer. The fine spaces include a first region and a second region that is below the first region. The second region includes a protrusion protruding in a direction substantially parallel to the substrate with respect to the first region. An alignment layer is disposed on an inner surface of each of the fine spaces. Liquid crystal molecules fill each of the fine spaces.

Abstract: A display device including: a display panel; a light source providing light to the display panel; and a color conversion unit converting a color of the light incident from the light source into a different color. The color conversion unit includes: a first color converting member, a second color converting member, and a third color converting member, located on a substrate, which convert the color of the light incident from the light source into different colors from each other, respectively, and output the lights having converted colors; and a blue light blocking filter located to overlap the second color converting member and the third color converting member. The blue light blocking filter is thicker at a boundary portion than at a center portion thereof.
