Abstract: A display apparatus includes a backlight unit generating light and a display substrate displaying an image using the light. The display substrate includes a substrate, a first electrode, a light blocking layer, a thin film transistor, a second electrode, a liquid crystal and a color filter. The substrate includes a pixel area and a non-pixel area, the first electrode is in the pixel area, and the light blocking layer is in the non-pixel area to block the light. The thin film transistor is on the light blocking layer and electrically connected to the first electrode. The second electrode faces the first electrode, and a cavity is defined therebetween. The liquid crystal is in the cavity, the color filter is on the second electrode, and the color filter is closer to the backlight unit than the substrate.
