A new and distinct Hybrid Tea rose plant having attractive pink and white bicolor flowers. The wearable display apparatus has a main control unit outputting view display position adjustment information corresponding to inputted interpupillary distance setting information and display units display-processing image information inputted to an area within a display region which is smaller than an entire view display area corresponding to the view display position adjustment information. , a III-V semiconductor material on a silicon substrate, comprises: preparing a surface of the silicon substrate with measures including passivating the substrate surface by HF etching, so that the substrate surface is essentially atomically flat. Such a circuit can automatically detect the phase error in the pixel clock and correct this error, thus eliminating the need for a manual phase-error corrector.
