Abstract: The object of the present invention is to provide a transmission type display device which is composed of a light source having plural emission colors and which can control the chromaticity of display images, maintain it with high precision, and be manufactured at low cost by easing the spectral sensitivity requirements required for the chromaticity sensor.

Abstract: In a transflective liquid crystal display device including a transmissive portion and a reflective portion in each pixel, the width of portions of a black matrix that are opposed to respective side portions of the transmissive portion is set greater than the width of portions of the black matrix that are opposed to respective side portions of the reflective portion. This measure prevents a phenomenon that leakage light coming from slant portions located on both sides of the transmissive portion or specular reflective light coming from flat portions would otherwise be mixed into reflective light from the reflective portion. As a result, highly legible, high-quality display without any glare can be realized. Contrast ratio evaluation results were such that the contrast ratio was 74 in the reflective mode and 194 in the transmissive mode. That is, high-contrast display was obtained in both of the reflective mode and the transmissive mode.

Abstract: The liquid crystal display device has red, green, and blue LEDs, each emitting a different color light, as a light source. An acrylic lens is mounted on the emission surface of the LED to change angular distributions of light from the LED. The shape of the acrylic lens varies depending on the color of the LED. The angular distribution of emitting light thereby differs by the color of LED to cancel out wavelength dependency of transmittance at each viewing direction in a liquid crystal panel.
