Abstract
A liquid crystal panel (10) comprises a liquid crystal injection port (12) for injecting liquid crystal between a pair of substrates, wherein a metal pattern (16) capable of reflecting infrared is provided in a region for providing a sealing resin for sealing the liquid crystal injection port (12).
Claims16
A liquid crystal panel comprising:
- a pair of substrates disposed opposite to each other;
- an liquid crystal injection port for injecting liquid crystal between the pair of substrates;
- and
- an infrared reflector capable of reflecting infrared;
- the infrared reflector being provided in a region for providing therein a sealing resin for sealing the liquid crystal injection port,
- wherein the infrared reflector is a metal pattern provided on any one of the pair of substrates, and
- wherein the pair of substrates is a TFT glass substrate on which TFT elements are provided and a CF glass substrate on which a color filter is provided, and
- the metal pattern is formed on the TFT glass substrate.

A method for inspecting a sealing resin provided to seal a liquid crystal injection port of a liquid crystal panel including a pair of substrates disposed opposite to each other;
- and the liquid crystal injection port for injecting liquid crystal between the pair of substrates,
- the method comprising the step of:
- measuring infrared light by using a Fourier transform infrared spectrophotometer, the infrared light being transmissive through the sealing resin and being reflected by an infrared reflector capable of reflecting infrared, the infrared reflector being provided in a region for providing therein the sealing resin for sealing the liquid crystal injection port,
- wherein the infrared light is transmitted through a glass substrate, and
- in the step of measuring by using the Fourier transform infrared spectrophotometer, the measurement is carried out with compensation on variation caused when the infrared light is transmitted through the glass substrate.
