  • Publication number: 20140043551
    Abstract: In the step of curing a resin for bonding a TFT substrate and a counter substrate each having an alignment film that has been optically aligned by using UV-light, damage to the alignment film due to the UV-light can be prevented without using a light shielding mask. A UV-light absorption layer is formed between each black matrix on the counter substrate. The TFT and counter substrates are sealed at their periphery by a resin that is cured by UV-light radiated from the counter substrate side. Since the absorption layer has a high absorbability to UV-light at a wavelength of 300 nm or less that degrades the alignment film, damage to the alignment film due to the UV-light for curing the resin can be prevented. Thus, provision of a light shielding mask for shielding the UV-light for the display region can be saved.

    Abstract: A TFT 1 is formed on a glass substrate 11, and a flattening resin film 17 covering the TFT 1 is formed. Furthermore, a moisture-proof protective film 18 covering the entire surface of the flattening resin film 17 is formed. For the protective film 18, a SiO2 film, a SiN film, a SiON film, or a stacked film thereof is used. The edge surfaces of the flattening resin film 17 are disposed on the inner side of or under a seal 4, and are formed in a tapered shape. By this, the entry of moisture into the flattening resin film 17 is prevented, preventing display degradation. This effect becomes noticeable in a display device including an oxide semiconductor TFT.

  • Patent number: 8625038
    Abstract: A data signal voltage on a signal line 102 is held in a voltage holding capacitor 106 through an n-type MOS transistor 103 switched on by a gate scan voltage, and supplied to an analog amplifier circuit 104-1. The analog amplifier circuit 104-1 is formed of an MOS transistor having a double gate structure, and the operating point thereof is set at an operating range in which dependence of Ids on Vds is substantially nullified. Even when Vds is varied due to a response of liquid crystal 109, Ids is substantially fixed. Accordingly, the pixel voltage which is substantially proportional to the data signal voltage can be applied to the liquid crystal 109.
