Description

technical field [0001] The present invention relates to a liquid crystalline resin composition for camera modules and a camera module using the same. Background technique [0002] Liquid crystalline resins represented by liquid crystalline polyester resins have excellent mechanical strength, heat resistance, chemical resistance, electrical properties, etc. in a well-balanced manner, and also have excellent dimensional stability, so they are widely used as High-performance engineering plastics. Recently, liquid crystalline resins are used for precision instrument parts by making effective use of these characteristics. [0003] In the case of precision instruments, especially optical instruments with lenses or the like, slight rubbish, dust, etc. can also affect the performance of the instrument. For example, in a component used in an optical device such as a camera module, when minute dirt, oil, or dust adheres to the lens, the optical characteristics of the camera module s...
