  • Publication number: 20240049552
    Abstract: A display device includes a display substrate and a color conversion substrate. The color conversion substrate includes: a second base substrate in which first to third light transmitting areas, and a light blocking area between adjacent light transmitting areas are defined, a first bank in the light blocking area, a first low refractive index layer between the second base substrate and the display substrate and covering the first bank. The color conversion substrate further includes a first wavelength conversion pattern in the first light transmitting area, a second wavelength conversion pattern in the second light transmitting area, and a light transmission pattern in the third light transmitting area, which are between the first low refractive index layer and the display substrate. The first low refractive index layer has a refractive index lower than at least one of the first wavelength conversion pattern or the second wavelength conversion pattern.

  • Publication number: 20160178942
    Abstract: In a method of forming an alignment layer, a first substrate, a second substrate opposite to the first substrate and a liquid crystal layer including a reactive mesogen are formed on a stage on which a groove is formed. The liquid crystal layer is disposed between the first and second substrates. An alignment layer is formed by exposing the liquid crystal layer to harden the reactive mesogen. Although the first and second substrates have a curved shape, the pretilt angles of the first and second alignment layers are matched such that a transmittance of the display panel increases and a response time decreases.

  • Patent number: 9275593
    Abstract: In one embodiment, a display panel includes a substrate and a gate driver disposed on the substrate. The gate driver comprises a wiring unit which receives signals and a circuit unit which outputs driving signals in response to the signals received from the wiring unit. The circuit unit comprises a shift register and a shift register wiring connected to the shift register. The wiring unit comprises first through n-th signal lines (n is a natural number greater than two) arranged sequentially adjacent to the shift register. The first line is located farthest from the shift register and the n-th signal line is closest from the shift register. Further, the first signal line is electrically connected to the shift register by a first connection line that comprises a first contact portion connected to the first signal line and a second contact portion connected to the shift resistor wiring.
